Two weeks yesterday for me - appetite was really only an issue the first couple of days....now I'm eating well (have a sweets craving occasionally, but that's normal when you give up alcohol), but sleep is still an issue. I work nights mostly, but occasionally days and evenings, so that in itself is a challenge.
I've been binging on some Netflix and exercising, both of which are helping the sleep issue some.
Hope that helps - welcome !
