birth control
"I hate to be one of the many negative commenters on here, but I want others to know my side effects that were related to the ring, that i didn't at first think was related to it.

Severe anxiety and racing heart. back pain. Zero sex drive! My alcohol tolerance down to zero with severe vomiting, shivering and hangovers. VERY moody especially week before period. 

I have been off all birth control for about 2-3 weeks...ALL symptoms have disappeared...amazingly...and now I know it's related to the birth control, not me going insane."
