Insomnia was pretty normal for me after I quit, but if you're drinking two bottles of wine of a night this might be a different thing?
I don't want to sound harsh but 2 bottles a night isn't really tapering...it's pretty much drinking - maybe not as much as you're used to, but still drinking.
I really think there has to be a better way to deal with your life than drinking.
Did you see your shrink?
