I am a 21 years male and I am suffering from Tuberculosis, my eight months medication is over and last month drugs are ongoing. I take rifampicin, isoniazid 600 and combutol 1000 daily and regularly . Since last 3 months I have lost interest in alcohol and whenever I am with my friends and I take 1 or 2 peg of alcohol after half an hour later I start vomiting . My Liver function tests are normal everything is fine with my body but I cannot understand that before taking this medication I often drank 5-6 peg of alcohol but never vomited and now vomiting problem creates a huge embarrassment for me, well since last 3 months I had alcohol for only 3 times and all the three times I have vomited.
