I was so excited to start this diet. My mother, father and a few friends had great success and wt loss so I decided to try it out to lose those last 30#. I had previously lost about 40# over the year through better food choices and excersise. I ordered the Sublingual HCG Drops and B12 Drops. On the Load days I gorged and stuffed myself full of high fat foods that I was litterally sick for 5 days, to the point that I couldn't think of anything but puking. My mom said that wasn't normal. I had gained 4# after the load days and it took a few days to get down to my actual start wt. Talk about disappointing! Then I lost a few # here and there and stalled, gained, stalled, gained for Several days straight while sticking strictly to the diet and suggestions posted here. I increased my drops, added Magnesium and Potassium, got more sleep...nothing worked. I was so tired all the time and almost to the point of being lethargic. I was moody with the kids and hated who I was. I decided on day 20 that I would quit something for the first time in my life because it just wasn't safe anymore. I wasn't safe at work, driving or caring for my kids. But then I did a little online browsing to see if the Phentermine sitting in my cupboard that I hadn't used was compatible with HCG. I got answers favoring both Yes and No, so I decided to experiment.....AND SO GLAD I DID!
What I am doing is taking my Phentermine in the morning after I pee and weigh myself. Then before bed I take 24 drops. I lost .6 oz the first day (and it was the first time in a week I had lost any weight, so I was so happy). Then the next day I lost 3#, then another # and so on. I am not having any side effects that I can feel from it. I have energy (probably from the Phentermine too). Plus I have not been strict with the diet. I keep my food choices simliar, but do vary sometimes. For example I will have a bowl of Fiber One or Banana Cherios for breakfast, or have a turkey sandwich on whole wheat bread with low cal dijon mustard. Those are the foods I ate pre-HCG diet. I have enough energy to resume my spin class at the gym now too, and feel like my body is loving me again.And the weight is going down, so I am happy.
I am not recommending anyone else to do what I am doing. I am just finally ok with my decision to vary from the "rules" and do something that is working for me! Plus I don't have crazy cravings for foods I know I can't have, even if I didn't really want them anyhow.

Has anyone else done anything like this before? Will it come back to haunt me?

I agree with Jevequart, although I am not a doctor or nurse. I too have used phentermine for weight loss and had great results combining it with a low carb diet. The phenermine gave me energy and controlled my hunger allowing me to make better food choices which was low carb. If you are taking the Phentermine, there should be no reason to take HCG. I know some people do it the first few days, but that is because it takes a few days for many to lose the hunger. I am relatively new with HCG. This is my second round, the first I am not considering as successful as my weight loss was little and my hunger and weakness was above average the entire round. This round has been amazing...I feel great and average .5 per day, although I have had a gain or no loss a few days of the two weeks I have been on. I am very curious to see the long term result of the HCG and the only way is to stick to the protocal. You can't take phentermine forever...it is can addictive for some and damaging to your body. HCG done properly seems to be the way to go. I have lost many cravings that I never thought I would. I consider myself one of little will power when it comes to foods. The few people who I know personally on HCG say that they too have lost cravings after going through the phases by the protocal.

Good luck with your choices. I look forward to reading what the "experts" on this forum think about your experience.

I am interested in seeing what Grammy thinks of this...

I agree with Grammy only because I've done the rx before and now am doing drops. I had some severe hunger on about the 5th day because I wasn't taking enough drops 10x3. On day 6 I "cheated" and had 2 oz of cheese, 200gms of chicken and 2 grissinis. If the hHCG was not working I should have lost weight because I only ate about 500 calories of food. But because the hHCG was working and releasing a couple of thousand calories into my bloodstream via abnormal fat, I gained almost 2lbs. Thats how I knew to just up my dose to 20x3 and not abandon the drops. The fat from the cheese did me in. The next day I was down 1.5 and am enjoing the non hunger and euphoria of the hHCG.

ok so i will be talked about putting thisout there but I successfully lost 35lbs using the phentermine and hcg together. i have also been able to keep this off in the long run. but i do agree that if u r hungry w/out the phentermine there IS a problem. maybe stop taking it til u get the hcg part down, then add it back in. i agree that it MAY be masking the hungries, but just find out. you won't want to waste any time on trying the hcg if it won't ultimately effect your settin gpoint at the end. good luck!
