Hi, I drink around 6 8oz red bulls a day. For the last year I have been having trouble urinating and it s only getting worse. I have to push so hard and then suck in my urine back in and do this over and over until I can finally pee. So, I m wondering if red bull can cause this or if I have something else going on. Also, the last 3 months, I wake up every night and have to pee really bad. Thanks!
