"i started phentermine on 7/24/15 at 379.5lbs. today i weighed in at 363. for a total loss of 16.5lbs in 7 days. the first day i was extremely nauseous, highly energetic, cranky and had dry mouth. the dry mouth and crankiness went away after the first day. i generally eat 2-300 calories and a 300 calorie protein shake with 52g of protein. i supplement with various vitamins and work out. i am hoping to lose another 10 in the next month. overall i am not even slightly hungry although my disgust for food is starting to wain. example of meal: half a piece of cheese, one turkey slice, half a cracker; then i am done. hoping i can tolerate 2 protein shakes by next week. working great so far."
