Hello, alcohol consumption can lead to Gastrointestinal upset and
gastritis, and that could be one of the reasons for your discomfort. To avoid that, you need to cut down on alcohol consumption, and eat properly whenever you consume alcohol.
Another factor is the stress factor which you have mentioned. Stress leads to IRRITABLE BOWEL SYNDROME(IBS) which causes loose stools, abdominal discomfort etc. You should learn
stress management either by
yoga or excercise. Also, antidepressants like SSRI drugs(
duloxetine etc) are another way of treating IBS.
Either way, first thing to do when you have loose stools is maintain hydration. Eat fibre rich food( green leafy vegetables) on a daily basis which will help in stool formation. Also, Tablet eldopar and tablet sporolac ds are the medications which reduce frequency of loose stools. But these tablets should be AVOIDED if you have
abdominal pain or fever( which indicate infection). Antibiotics are recommended if symptoms of infection are present.
Remember to drink PLENTY OF FLUIDS.
