I've been working ever since takedown 6x a week without issues. I stay cautious of the hydration part as sometimes its easy to get dehydrated without even knowing, so I carry a big bottle of plain water or add some creatine and BCAA to fuel the workout. I think its something you ate thats caused some reaction . Maybe food poisoning ? I'd get checked for that.
Also anytime I feel diarroeha like or not well overall I switch to a plain diet full of bananas, brown bread with butter, nut butters (smooth), chicken and eggs, rice and milk.
If you're having mild issues now you can try altering to a bland diet for 1-2 days. Most of the time it works.
