Keep it up. The alternative you well know, so changing direction is your best choice. Sleep will happen in time. Try taking B vitamins and calcium/magnesium. 5 HTP (tryptophan is a safe amino acid found in health or drug stores), melatonin, camomile or other sleep herbals. The sleeplessness will pass with increasing time sober.

Listen to Jimi. He knows all about it. Keep posting! Good luck to all.
