^^^ an increase in metformin is definitely worth looking into. I started at 1000 mg per day (500 twice a day). My hair stopped falling out but I didn't regain my cycles until I was increased to 2000 mg per day (1000 twice a day).

I was on Phentermine in 2009. I lost 65 lbs and kept it off for a year and half. My eating habits stayed the same only my workouts changed a bit. Needless to say, I've gained it all back plus some and I now have a MVR (my former doctor thinks it's from Phentermine). I just moved so, I'll see a new doctor to get a second opinion. I won't go back on Phentermine UNLESS my new doctor deems it's safe but, I don't think that will happen. While I was on it, I rarely had any appetite, I was always tired and thirsty. A lot of my nutrient levels dropped to the point I had to have prescription vitamins because otc vitamins didn't have enough. I couldn't eat any meat products, I would get super sick and anything with sugar would give me headaches.I'm extremely sensitive to medication so, what I experience isn't what many people would experience. That's the thing about any medication prescribed or not, everyones body reacts differently so what make work for another doesn't always work in the same way as it would for someone else.

I don't take metformin. At all. I gained SO much weight on it. I'm also not Insulin resistance. I have polycystic ovaries but that's it. My last bloodwork in Oct showed that I'm not IR. I haven't been on metformin since 2008.

I tried Phentermine and just stopped recently when my insurance changed and it got more expensive for me. There were some big pros and cons to it for me.

Pros:
- I lost weight quickly, and that was a great motivation for me to keep going
- It definitely suppressed my appetite and helped me to not eat or even crave unhealthy food
- It worked consistently over time

Cons:
- It made me extremely emotional, and even aggressive
- When I stopped taking it I had intense cravings and immediately began to gain weight
- Awful headaches

The first month for me was the worst. I didn't even know if I would be able to make it through the emotional roller coaster, but once I got past that it slowly got better and better. Not everyone has these side effects, and some people say that they feel great and have more energy.

Now I am working on losing without phentermine and it's hard, and I've considered starting up again. But that dreaded first month… ahhhh! Also, I really want to get pregnant and would prefer not to be on phentermine when I do conceive. Hope this helps, and good luck!
