Soma is a strange drug, I have been prescribed it 20 plus 2 refills for ten years. Why they just do not give me 60 is beyond me. I had a stomach bleed from NSAIDS about 10 years ago.I have chronic pain. So I get Soma and T-3s,My doc is scared of hydrocodone. He says its not that bad but it has a bad rep. The Soma and T-3 work very well but sometimes togeather they really put me out there. I am carefull not to drive,and work on them. Some times soma on an empty stomach can really get you. I have found tolerence is an issue with both drugs.I have had all differnt brands of Soma.The only difference I find is duration of pain killing. The ones that hit you fast do not last,the others take their time and last longer.Just my experience,everyones got a differnt make up.
