"i&#039;m probably not qualified to review this as i only had it in for 24 hours. i mistakenly read the reviews/side effects after getting it inserted and immediately regretted getting it. even though i know i might not have experienced the adverse side effects, i was not willing to risk it. i will definitely do more research next time! 
for the 24 hours i had it, i did feel quite nauseous and nearly fainted twice. other than that, the insertion and removal was fairly painless."
