Stomach issues on day 5-?

I quit smoking before and my withdrawal symptoms were more emotional, nightmares and sweats. The second time quitting now on day 6, is somewhat emotional but mainly having headaches and constant diarrhea , I know for the headaches that Tylenol and water are the best, not sure how to deal with the stomach issues though. Any tips? Also I’m going to the movies alone today to distract myself and also cross that experience off my bucket list. Any tips for when I’m at home for the boredom would be helpful as well, I have a diamond painting I can do but that’s all I can think of.
