If I eat alot of raw fruits and veggies I would have a problem the next day. If he isn't used to that much fiber it can really do a number on him. Also all the hard work and heat can take a toll on someone not used to that which may have factored in to why he felt so tired any woozy. However, if he has this kind of thing happen at other times and you can't attribute it to certain foods then it really would be a good thing to have him see a GI. He certainly shouldn't be having diarrhea every morning.
