Hi Pearl,
Congrats on day 2. I know that eating a balanced diet is good and getting plenty of sleep, but don't know about specific vitamins. I kid you not, but in my earliest days, I ate a ton of red vine licorice. Not recommending this by any stretch, but it did quell my cravings. Lots of sleep really helped me (and still does, since I am in early recovery too). Have you looked into AA? It has really helped me.
Jup.
