"i have been on 37.5 for 3 weeks now, although it gave me more energy the first week, that has subsided and my appetite comes and goes. i have only lost 2 pounds in 3 weeks but i believe that to be from the new exercising. i&#039;ve always drank a ton of water because i love water so the only change is now i have dry mouth to tend to. i weighed 285lbs and my goal was 220lbs because i do like my curves just not so many. i do not eat as many calories as recommended on certain days because i am literally not hungry buy on other days i may go over by 20-30. but 3lbs? really!! i&#039;m frustrated"
