Meprozine and drink taste

I have had 4 surgeries on heal over a 15 month period and everytime I have been given meprozine. I am not a pill popper so normally do not have a problem because I do not want to take a chance of taking something that will get me hooked on it. This surgery was different I decided what the heck I did not want to suffer the pain that I had previously if I did not have to. I have had a couple of instances that I had twitching, but the major side effect id this ungodly taste in my mouth that makes everything I eat or drink taste nasty. Other than that I have had no side effect. But will change to Propoxy which only seems to dull the pain but at least I can enjoy eating again.
