For diarrhea: Lemon water. I have found that drinking lemon water has stopped my 6 months of diarrhea. This is amazing. One 16 oz water bottle( drink some to make room for juice), squeeze one fresh lemon, pour into water bottle. Sip all day. Then do this again the next day and sip on this one bottle for 2 days. Keep making one bottle last 2days and always drink with a straw as to not damage teeth. Best results after about two weeks. This drink also alkalizes your body. Lemon turns into an alkaline after ingested.
Bonus: sleeping through the night.
