Welcome wwd2!
Take it slow, be patient with yourself, and I hope you consider checking in with a doc, as alcohol withdrawal can have some serious effects. However, if you prefer to go it alone, know that there is a great deal of support. Stock up on multi-vitamins and the supplement melatonin helps with sleep.
Your wife is probably just concerned, and expresses her concern as what we percieve condesending, because afterall they are usualy right, right? *S*... and somebody has to be brutally honest with us, since we don't have the capacity to do so.
I hope you'll stick around! You've got a great community of support just a click away!
