Aspirin and alcohol, taken together, equates to a caustic hell on my stomach. Alone, I can tolerate either without much issue, gastronomically speaking. The first time I was negligent enough to mix both, I had a about a gram of aspirin mid-day and few drinks, maybe 3 or 4, that night. Big mistake. I spent the next week on toilet suffering through constant diarrhea and intense stomach pain which I can only assume to be ulcers. I couldn't stay away form the toilet for more than an hour or two at a time, and was literally unable to leave the house due to a combination of pain-induced misery and a thrice validated fear of being unable to contain my bowels. This physical torture combined with the comparable degree of mental instability achieved via long term Propecia side-effects really tested the limits of my sanity throughout the entire experience. So there's my word of warning.
