"i was really excited about getting back on birth control, as i have had negative experiences with the pill. after less than 24 hours, i could tell a huge change in the way i felt, overall. i had a pounding headache, i felt like i had not slept in three days, and i wanted to eat everything in sight. i tried to stick it out, but after a week, i gave up and decided to take it out. all of the symptoms vanished within 2-3 days."
