I Take Trazidone At Night For Insomnia, Which Works Great.

I take trazidone at night for insomnia, which works great. I have no problems getting up in morning. I was taken off opiates,? which is fine i know opiates can be dangerous. So I take methocarbamol. For a muscle relaxer for spasms in my back but it is a bone problem not a muscle problem I have had many x rays and next week I will be getting a( shot in my back) ever since they took the opiates away I have been given Methocarbamol, carbidopa levadopa, I have taken medcations for years such as paxil, colonipan I was taking these meds. LIke forever but know I talk funny I fall a lot like my legs are turning to jello. Please help me figure out which meds I should not be taking together.
