Since I stumbled upon the word "Phentermine" in a diet forum on another site, and realized that folks are using it alone, I've done some research and decided to give it a shot myself. (Ordered via an on-line pharmacy, and yes, I plan to inform my doctor). What I'm curious about, is what the dosage difference is between what doctors were prescribing years ago, with the Phen-Fen combo vs. the current usage of 30 mg. or 37.5 mg. once a day of just Phentermine? 7 years ago, I felt fantastic on the Phen-Fen, lost 35 lbs., felt like I could conquer the world, then I went off of it. I was going through some life-trauma stuff, and turned back to food, and I hope that this time, once I get to my goal, I will have my wits about me and will have learned to use other methods in times of stress (exercise, meditation, counselling, etc.). Of course, I was concerned and saddened to hear of some women getting heart-valve problems as a result of the Phen-Fen, but I wondered if those problems were pre-existing and dormant? I confess to missing the relief those drugs gave me. Anyway, the battle of food-obsession, and being overweight continues. I figure, by the time I'm 90 years old and on my death bed, a wonder weight-loss drug will finally be approved and overweight will be a thing of the past.
