Although I stopped having real cravings after about 3 months, I really started feeling more grounded around 8 to 9 months, when my neuropathy finally started to get less painful. In the beginning, it actually became much worse (this is not uncommon), which was a real challenge to my sanity to say the least.
I chose 6 months, but in reality it was 9. But that doesn't really matter in the grand scheme of things; it's clear that for many it takes a bit of sober time to get used to the new situation.
