Sorry about your poor sleep and vivid dreams Could definitely be related to your cutting back. I read that drinking 24 ounces of wine a day for a year or longer will indicate likelihood of withdrawal issues. A regular size bottle of wine has just over 25 ounces. I did not know this information prior to quitting my daily intake of a bottle or more of wine. I did not taper. Had three weeks of not feeling well, And now I know it was withdrawal after reading up. Very scary. Good to report that after the first weeks, it gets better and better every day. Best wishes to you in finding the life you want.
