First and foremost....BIG congrats on your one month off opiates!!!
I know you had 6 months once before and recall some of your story, just want to make sure you've cut off all your sources for them so you don't end up taking "just oneforfun"..LOL Sounds like you are doing really good and beginning to enjoy some of the benefits of making it back to the other side☺
As far as the carisoprodol (also known as Soma)....if I were you, I would NOT take it. I speak from experience here. Even though it is a muscle relaxer, chemically speaking, it breaks down similar to a benzo in our systems. (Getting rid of them would be a good idea) That's why your red flags went up. Good on ya!
It was changed to a Schedule IV Controlled Substance in January 2012.
I am truly surprised your dr knows of your addiction to hydrocodone and still prescribed this to you. For muscle spasms, two other muscle relaxers that aren't addictive that would work are: Flexeril and Baclofen You could call your dr and get one of those called in for your muscle spasms.
Hope this helps you.....and once again, congrats on your one month opiate free☺☺
You should google caridisopodol and get as much info as you can. It definitely is abused and people become dependent upon it. It's taken alone and also with opiates. If you can do without I'd really stay away from it.
