I've been drinking energy drinks everyday for the last 11 months. This morning I went for a poo and went to wipe to find bright red blood.

Rectal blood. May be unrelated, may be hemorrhoid but would follow up with doctor as could be polyp, inflammatory or food reaction. In general energy drinks can be quite dangerous , the caffeine content is very high and they contain other substances as well. Would stop the energy drinks can develop palpitations , tremors anxiety and a host of issues. f/u w/doc.
