Hi Zab, I have been following your journey and thank you for posting each.day. it helps me and others more than you know.
For sleep, a natural remedy is Melatonin, which can be bought a any pharmacy or health store.
As for general uneasiness, headaches, shakes, cramps,. take some Magnesium.
Also, since Alcohol robs us of potassium, so do eat a banana a day.
You are doing great!
