"i have been on just about every pill/needle contraceptive out there and usually all the side affects take about a year to show up. i was on depo needle for 2 years and loved it but my doctor made a point of mentioning every 3 months that i should go off of it. now thislovely little pill - destroyed my sex drive within the first 3 months, only positive is that i grew a cup size over night. downfall, gained 23 pounds over 6 months. constant bloating and took 5 months for my period to regulate. another bad side affect is i no longer sleep longer than 5 hours a night when i am known for sleeping like a log (and night sweats are so bad i wake up soaking to the point i have to change my clothes and sheets)never had that before in my life."
