"i started the 37.5 on 10/15/16 and i felt the jitters and the nausea. i did not feel the burst of energy. i only ate 600 calories on day one. today is 10/16/16 and i feel more hungry then day 1. i ate a total of 1400 calories today.  i did have a lot of energy....i actually washed baseboards and all. i hope it continues to curb my appetite. so far no bad reports"
