I was for many yrs. Now alls I can drink is 1 coffee in the morn and nothing but Gatorade G2 from then on. I got a bad stomach attack 2 yrs in a row and the only thing the docs could blame it on was sodas and beer. I havent drank any beer in 5 yrs now so it had to be the dew and other sodas. I was drinking 6 or more cans a day. I was always on the go! lol
