I don't mean to alarm you ma6907 but is it possible you are experiencing DT's? I remember you are on Vivitrol so your opioid receptors are being blocked 24/7 so you should be used to that by now. Has the only thing that has changed is trying to go AF? DT's are no joke. You can read about it here.
http://en.wikipedia.org/wiki/Delirium_tremens. When you've had AF days in the past did you experience withdrawal symptoms? Please keep your physician in the loop on what's going on. Presumably if they prescribed you Vivitrol they know how to deal with withdrawal symptoms. That is the nice thing about TSM is you can detox slowly over time not cold turkey which can be dangerous for some. Take care.
