I've been taking Soma (carisoprodol) and Vicodin NORCOS for the last year. Some days i would take up to 9 Somas in three pill intervals and other days i would take up to 14 Vicodin. This is all due to a fusion in my back. Every time I kick the pills i get diarrhea really bad and stomach pains. I was off for two weeks but still had that diarrhea. Has anyone took this combination and if they have or just took SOMAS can you help me or tell my if it gets better. My Doc said its fine but I think hes a quack.
