I am detoxing from alcohol?

I am detoxing from alcohol
I am taking 2.5 mg of diazepam as needed
Also magnesium and vitamin b supplements. Have been drinking about four beers and some wine for several days. I was wondering if I could take 5htp, gaba or l glutime to ease symptoms. I am 1000 miles away from home my symptoms are lack of appetite and fatigue

Age: 64
Medications: Diazepam for essential tremor
