Alright brothers so i have a problem.

I'm 6'9 and been cursed with a fast metabolism i need to eat atleast 5,500 - 6,000 calories being inactive just not to lose weight (srs)

Add exercise and wanting to bulk and i need to go up much more than that. After about eating 4k calories my stomach can't handle it anymore. Bloating, gassing you name it.

Anyone here have/had the same problem that can share some tips? Whatever it may be a drug/pill that helped or anything else really.
