I have been sober for one year and I have noticed PAWS symptoms peaked for me at 9 months. At 9 months I had some days during which I felt completely unprepared for anything, big or small. It felt like I didn't have my brain attached to my body.
I think weight can fluctuate due to stress and poor eating habits. When I first attempted sobriety I lost weight but I was exercising a lot. Now I am trying to return to exercising and I feel more lethargic these days.
PAWS I think can take up to 2 years to become manageable. Right now I'm not taking any anxiety medication because I want to focus on being naturally healthy.
Also, I know for me that reading things on the internet over, and over, and over is not healthy. Sometimes I need to just sit back and quit analyzing everything. I hope you feel better soon.
