okay, well three weeks ago my doctor prescribed me to start taking Mirtizapine, as I have severe depression and sleeping problems. The first few days on the medicine, I was like.a.zombie ! I couldn't get out of bed for hours, I couldn't walk around without flopping back in bed again, and I wasn't interested in food at all. for the next few days I was very tired but still went to school. Now three weeks later I can't stop eating ! And have gained THREE KILOS :/. What is happening ? Is this meant to happen ? My doctor never told me about the weight gain.. Any tips ? Or anything ? Help will be much appreciated !! X
