This is my third day on it and I nearly passed out today for no reason. I know that dizziness is a common side effect but my head started feeling really fuzzy, then my heart rate went up and I started having sort of tunnel vision/sounds fading out. I made it to the couch and then started dry heaving for like a minute. ( I have constant stomach problems so idk if its related to that) 

Anyway if anyone else has experienced this and maybe knows if I should be worried that'd be great. Also if it matters I usually take it around 3am, and this happened at about 7pm.
