Birth Control
"It does as it should: it prevents pregnancy.  Other than that I&#039;ve gained weight and struggled to lose (still haven&#039;t and still struggling). My mood swings are awful. I bleed for up to two weeks at a time, although no cramps. My sleep pattern is erratic and I wake for two hours nightly and almost always lethargic and no energy or motivation. My appetite is ferocious. I also lost my sex drive which negated its purpose. I&#039;ve since had the coil put in and awaiting to see if things will improve."
