Hang in there Unwound. 6 weeks is great, keep up the good work. Bottom line is this is tough. I quit smoking years back too and in my opinion, quitting drinking was much tougher on me for sure.
Try to find avenues for when you are having tough times or when your cravings kick in. Walking the dog is great, are there any other things you could do to take your mind off of drinking?
You are still very early into recovery, your body and mind are still adjusting and will be for some time.
Don't ever give in, keep riding your recovery. I promise, all of the tough times now will be worth it soon. Quitting was the hardest but best thing I have ever done for myself and my family.
Hang tough and stick close to this community.
