I have been on yasmin for two months now and could tell the first week of the first month that I had became extremely angry at everything. This could almost be described as rage. This abated by the second week but then nausea would consume me and an achy body - particularly in the pelvic region, lower back, and legs. I chalked it up to the flu. Additionally, I experienced night sweats (big time) and something akin to anxiety and "jitteriness" - almost like having a caffeine overload ALL THE TIME. The second month I was on yasmin, my reaction was identical. Rage and anger and now here I am, feeling like I have the flu. I am so incredibly achy and have severe nausea. I, too, also seem to have some effects due to dehydration and I am peeing constantly. I am stopping yasmin as of right now - particularly after reading these posts. I was wondering if the fact that yasmin increases potassium levels had something to do with all of this. Now I REALLY wonder. I will post again once I determine how things go while off of yasmin.
