I have been taking Remeron for about 3 weeks now. At first, I thought it was awesome because I could sleep. But I'm sleeping about 12 hours a night, and still feel groggy all day. I've gained 6 lbs. in less than two weeks. I have breakouts of sweating, compulsive eating, anxiety, and I feel like my heart is racing all over the place, even in my throat. My doctor increased my dosage and said to give it another 6 to 8 weeks. I don't feel any difference in my mood, maybe a little more irritable at times. I am confused and don't know what to do.
