1) See a general physician or internal medicine specialist first - not a specialist for each symptom. Carry these tests: HbA1c, fasting and post-meal blood sugar, complete blood count, liver function tests, kidney function, TSH, vitamin B12, vitamin D, serum electrolytes and lipid profile, plus an ultrasound of the abdomen to look for fatty liver. 2) Diet: three regular meals with protein at each (eggs, dal, curd, paneer, chicken), stop sugar and refined carbohydrates, and do not skip breakfast - post-meal sugar swings are a big cause of your afternoon exhaustion. 3) Exercise 30-40 minutes a day, 5 days a week; brisk walking plus light weights twice a week reverses pre-diabetes better than any tablet at your stage. 4) Sleep 7-8 hours with a fixed schedule; alcohol withdrawal disturbs sleep for a few weeks. 5) Take supplements only after the reports - thiamine, B12 and vitamin D are commonly needed after quitting alcohol, but the dose should be individualised. 6) Recheck HbA1c and liver tests in 3 months; with weight loss of even 5-7% pre-diabetes is frequently reversible - that is the "permanent cure" you are asking about. I would be happy to go through your reports on a Practo online consult, or you can visit me at Synergy Multispeciality Hospital, Miraj.

Please do not restart alcohol to "feel better" - the relief is temporary and it will worsen both the fatigue and the sugar levels. If you develop tremors, sweating, confusion, palpitations, chest pain, breathlessness, yellowing of eyes, black stools or unexplained rapid weight loss, get checked the same day rather than waiting for reports.
