You'd be pissing every 10-15 minutes if you actually did that.
On non-training days I don't but on training days I do.
Funny you mention pissing even 20 minutes, Back in 2004 when I did my last show I was up at 3:30am for cardio and I had drank 2 gals by 10am and every 30 minutes I was ready to explode.
