Welcome and great job on a week plus!
Yes, I had all kinds of problems eating and sleeping at first. I needed to gain weight but I just wasn't hungry. That changed- I definitely got into the sugar thing around 2 months in.
I was EXHAUSTED at first. I was very sick when I quit; now, 405 days in, fatigue is still my number one concern as I live a very full life.
At the start, I took huge advantage of naps.
Taking care of yourself- learning to listen to what your body needs now that you are not putting alcohol in it is critical.
Good luck.
