This gets asked a lot, understandably. If it continues get a blood workup. Have them check magnesium levels, other electrolytes, Thiamine etc. Tell them you're an alcoholic and they will know what to look for.
I was very low magnesium and it was causing me a host of problems that mimic detox....but it was happening weeks after actual detox. Rebuilding my levels was challenging with diet alone so I was supplemented and it worked wonders. Everyone is different however so I don't recommend randomly guessing at what your body is lacking.
