I Have A Digestion Problem. I Go The Toilet At

I have a digestion problem. I go the toilet at least six times in a day. Morning at least 4 times and then again in the afternoon and one more time in the evening. I cannot work properly as I have to go the toilet again and again. My stools are also different through out the day. I have fissures also because of which it burns on the outer area where the stools pass. I have been drinking whiskey daily for the past 8 years. I cannot skip a single day without alcohol. What medicines can I have to cure my problems without leaving alcohol?
