I have just done my first month and thought that as soon as I stopped drinking I would be bouncing out of bed, be raring to go, full of energy, and exercising every day. Whereas, I found that I felt totally exhausted, had a headache every morning, and needed a sleep in the afternoon (not good when you are in a meeting :-) ), and could only do half of a group exercise class due to fatigue.
I then read that this is all normal and to bear with it. I have been eating nutritious food, staying hydrated, and resting as much as I can, in order to help my recovery.
I also thought that in order to stop drinking I would need to sort my sleep out, to sort my anxiety out, and to sort my boredom, agitation, an inability to relax out first. On the contrary, stopping drinking has enabled me to achieve these things. I cannot believe how much alcohol got in the way of things.
Well done on starting the process. It will and does get better.
