birth control
"I've had the Mirena for about 1 1/2 years.  At first I was very happy with it.  Didn't notice any weight gain although I noticed it was very hard to lose weight as I began working out a lot more and eating better so I should have lost weight.  I have just begun to notice within the last 9 months or so that I am slowly gaining weight, don't feel very good, severe bloating, tired, moody, no patience, depressed, and no sex drive at all.  It has finally dawned on me that all of this might be because of the Mirena and am getting it taken out.  All this time I have been thinking there is something wrong with me but now I have hope that once this is removed- I might go back to normal- or I hope I do."
