I think I might have to experiment a little further with different foods to see if it's just specific stuff that makes me feel like a bag of shit halfway through. So far it's been steak+veggies, and cereal that have done it - and only during push days, pull and legs don't seem as much effected. I don't think chicken bothers me too much.
Though lately since I haven't been eating after 1 - 2pm (workout at 6:30ish) I've been feeling fine. Kinda run low on energy, but certainly don't feel like a big blob that wants to spew for no good reason haha
