The reason I had to reply to this thread or why it caught my eye was because you mentioned withdrawal from Soma. My ex best friends mom who had been addicted to all sorts of RX meds, had a particularly very strong addiction to Soma (carisoprodol). She got clean, and at some point got back on them etc but i always wondered what were some of her withdrawal symptoms since she denied she had any (which i actually believed lol).
If you really feel like you have been defeated by your addiction, I would see a doctor or even better a psychiatrist and explain your situation and they might be able to prescribe you something to help you with the withdrawals.
I also have done Soma quiet a few times but on seperate occassions so I'm not sure for personal advice on dealing with the withdrawals. Another real good thing you could do is just go to google and type in soma withdrawal and i'm sure you will find hundreds of people and pages of people who have been addicted to soma and may know ways to get off it or help withdrawals.
