I'm sorry that I didn't see these responses after I had posted them.
The physical issues were related to another medical condition that had nothing to do with the withdrawal, and I appreciate the suggestions and insight.
I also appreciate the common-sense approach directly above. Addiction, in any form, is something to manage, not "cure," and I read too many entries and responses that insist that there is some one-and-done "cure." It's a lifelong thing, and doing "feel-good" activities is actually a wonderful suggestion - it takes away from the negative of addiction and replaces a positive and proactive thing to reinforce positive energy. Thank you, very much, for the sound and sensible responses! :-)
