I finish workout at 11pm+.. If i eat a lot then i get really tired and sleep straight away.. How bad it is to sleep after heavy meal?

Seriously too much reading end up confusing myself. Every forum/article say different thing. Maybe my english standard cannot understand them well. I don't know.

Sometimes next day I get upset stomach or the thing i scare most, food poisoning. Perhaps it has something to do with the food i ate?

So, now i stick with mass gainer + creatine. Too much protein also not so good cause I can't sleep well. Have to wake up at 5am~6am to pee.
