Stupid kid symptoms and conditions

My husband is suffering from a back injury, He has been prescribed, Soma, Zanaflex and Meprozine. Since being on these meds his moods have changed. He has become irritable, depressed, short tempered and very argumentative. He is not the man I married while he is on these meds and when he doesn't take them he is ok for a while but then is like some one on drugs who needs their next fix. I am very concerned for my husband and my family because he has started taking yelling at my daughter for stupid kid stuff and arguing and yelling at me about small stupid things like whether a valve was open under the kitchen sink. He has had a migraine for 3 weeks now... his appetite has decreased... he has been having weird dreams and twitching in his sleep.. He has also experienced dizziness, insomnia, restlessness and irritability. There are other side effects... I do not recommend these medications at all especially together....

My husband has been prescribed Meprozine for a back injury, and since he has been on it I have notice a major difference in his moods, he is edgy, and temperamental. He has started yelling at my daughter for stupid kid stuff and arguing with me over small things and we never argue. He has had weird dreams and twitches in his sleep. When he is on the medication he doesn't seem like the man I married and when he is off its like hes going through withdrawals and trying to go un-noticed. He is also on Soma and Zanaflex. I don't know what to do. Im worried for him. He is also becoming depressed, and has had a severe migraine for 3 weeks now. He wont listen to me when I tell him not to take it. I would not recommend this medication to anyone, especially if they want to keep their relationship.
