Been on it for only 2 wks and feel very BLOATED. Think i gained about 3 lbs. already. Prob water retention. I hate it!! I have more headaches and my vision seems blurry.. but could be due to my contacts being drier. I also have dry mouth. Feel like it's dehydrating me cause I'm prob retaining more water. Also have headaches, cramps and GAS!! Losing more hair than usual... feel pregnant with cravings for sweets.. but I'm not experiencing crazy mood swings... maybe not yet. Debating whether i should get off of it. No crazy discharge either.
