Hi Sarah. I don't think I was around to catch your first few posts and so here's a late welcome from me. I was extremely exhausted in the beginning also. I had not slept through the night in such a long time. I would pass out and then wake up in the middle of the night and did this for years. It felt so great to sleep soundly.
I have been taking the b supplements and a regular vitamin since I quit drinking. It really, really does help. Also just getting out and taking a nice vigorous walk helps too.
Any ways, just wanted to stop and say hello. Good for you and your 4 days. The first few days were the hardest. We'll be cheering you on and helping in any way we can.
