I was amazed and so was my doctor that I had no physical withdrawal issues. My consumption averaged 1.75 liters of scotch every three days.
Like you, difficulty sleeping has been issue since I have been sober, now 10+months. As I drank heavily in the evening, it obviously put me sleep rather fast. Overtime, it has become easier to go to sleep. I still awake in the middle of the night (bathroom call) whereas before I slept right through. I think this is just because I no longer pass-out with booze and now feel the sensations.
One thing that really helped me in the beginning to go to sleep was to mentally review the day in detail and then plan the next day. Maybe a boring life, but this generally, then and now, still puts me to sleep.
Keep up the good work. Taking in one day at a time, starts to add up really fast. Hey 300+ days now.
Just remember to stay involved each and every day. Recovery is now a fact of life and will be part each day forward if you desire to keep your sobriety.
