"i have been on it for less than a week. the first week is supposedly the hardest. i&#039;ve had a lot of lightheaded effects and a bit of nausea and muscle twitching. the more i give it a chance, the better i feel. i changed it up the last couple days and started doing the 150mg pill in increments, half a pill twice a day. it makes me feel much more balanced. i dont ever remember me having this much self control. it&#039;s amazing."
