Remeron and medicine

My mother has been on Remeron for four years. She started for depression and received the prescription from a psychiatrist. Our family raised questions about the drug with her psychiatrist after she began to have rage issues and became very disagreeable. My mother and her psychiatrist insisted the was doing fine on the medicine. Since that time things have only escalated. She now gets Remeron from her family doctor. She has become more and more enraged, throwing things and has gotten physical with my father, her husband of 46 years. He has been living with my sister for the past month because of her extreme behavior. She is estranged from all family, (except one son) and friends because of her behavior. We are very concerned for her. She has denied still taking Remeron but we did not believe this. And has recently found she has a newly filled prescription for 30mg.
I have called her doctor and relayed all of her extreme behavior. Just hope and pray he does not continue to prescribe this drug for her. It has torn my entire family apart. Any suggestions would be welcomed.

I have been on Remeron for last month, the first week was wonderful. I fell asleep for 12hrs the first night. The following nights of the first week were great, I slept like I hadn't in years. The third week it started to all crash down on me. I couldn't sleep, my legs felt like I had bugs crawling all over me, I kept my poor husband up all night, getting up and down, kicking and turning all night. I then started realizing I was angry over nothing. My mother is very sick and will not get better (one of the reason I started Remeron in the first place) and I am noticing I am irritated if she needs something or just calls to say hello. I don't want to talk to anyone, not my friends, husband or even my children. My son is a diabetic and I told my doctor if I took any medicine it couldn't just knock me out, I had to be coherent enough to take care of his needs. The medicine didn't bother me the first couple weeks. The third week, I would forget how much insulin to give him, and that is a scary feeling if you gave your son the right amount of medicine. I would think after I gave him his medicine, did I give him the right amount or am I going to make him go into shock. I also have gained weight, I have never liked sweets and that is all I think about. I go to dr. this week, hopefully she will find a new med that won't make me forget everything, want to be such a hag to everyone, and help with those crazy leg tingles. I was on 15 mgs to start out on, I even took an extra one the other night because of the leg tingles, and it made it worse. So I took an over the counter sleep aid and I finally fell asleep at 4:00 in morning. I am so glad I found the site, I thought I was losing my mind. Thank You to all of you, you have helped me tremendously.
