Ok, here's my experience:
Around 1995, I got a prescription from my dr. at the time (Adipex-brand name). I don't remember how much I weighed prior to starting, but at the time I had two toddlers that were born back-to-back, and I was still carrying around that baby weight. I'm guessing around 190 lbs.
Along with the pills, I severely restricted my food intake, and walked religiously on my treadmill. I quickly went to 140 lbs. I took the pills for approx. 6 months, and kept the weight off during that time. But within a year I was back up to my starting weight. This was due solely to the fact that I stopped writing down my daily intake.
At the time, the pills made me very hyper, to the point that later my husband expressed concern over my 'mania'. I however enjoyed the side effect very much, because I tended to be lethargic and depressed, and it was nice to be able to jump up and accomplish things!
Fast forward to January 2005. I was clocking in at 204 lbs. I had just had a hysterectomy a few months prior, and while digging around, the doctor found that I was accumulating fat around my liver. In Jan I made an appt with my family physician, for advice on a sound eating plan (and with the idea that I was going to ask for another prescription for Adipex). I did get the prescription, and this time, I didn't have the hyper feeling, but I did get a nice boost on the diet. So coupled with the diet plan that the dr. gave me (based on the American Diabetes Association diet), the pills gave me the headstart I needed. After three months I weaned myself off them, and used determination alone to help me. From Jan to Feb I lost 25 lbs, and Feb to Mar another 15. Without the pills, my weight loss slowed down drastically, but I was motivated to continue with my healthy habits.
Ok, long story short....if you decide to take the pills, just monitor your side effects. You might not enjoy the hyper feeling it gives you, or you might. (Your family probably won't) But each person has his/her own individual reaction, and no one can say what will or will not happen. For me, the first time I tried them it was a bust, but not due to the pills. Just due to my not understanding that these were life changes I needed to be making. In 2005, it was the best thing I could have done, because it kickstarted my weight loss, and my determination has kept me going. Today, a little over a year later, I feel so much better about myself and I'm MUCH healthier. I haven't been back to my gynecologist yet (I've been putting off my yearly appt,

), but I'm anxious for him to see the results!
