Phentermine
"I started taking Phentermine on 7/18/15 and today 9/17/15 I am down 30 lbs.  From 296 to 266!  I am doing it in conjunction with My Fitness Pal.  This way I know how many calories I intake.  Walking a bit but no major exercise program yet.  The only side effect is the dry mouth so I keep mints around to help and drink something.  I really recommend you track your food intake....that's the only way you are going to be able to know you are eating the right amount.  It's so easy on your smartphone too!"
