Phentermine
"I've been using phentermine for 3 weeks and I've lost 13 pounds with no exercise that being said I don't just sit around all day either. And I have not changed what I eat at all but it just makes me eat so much less and not be hungry. Also listen to the label when it says eat afterwards. Days when I took my pill on a empty stomach I felt tired and sluggish all day.  But once my stomach shrunk and I've gotten used to my new eating habit I have no problems other then the dry mouth gives me bad breath so I've been brushing like three times a day. Also I've been told that when you stop if you are not on a good diet and exercise schedule you will gain it all back.. Just something to keep in mind...overall great product!"
