I pee a lot. I take a diuretic for my heart and I do that 2 times a day. I have a catheter in me and I can fill my 1000 ml leg bag in a couple of hours after I take my pills. The other day I collected all my urine in a day, well most of the day, I almost filled a 4000 ml overnight bag.
I have to empty my leg bag at least 4 or 5 times a day. Usually drain my leg bag when I get about 400 to 600 ml of urine in it. Now and then I get the bag filled all the way to 1000 ml.
So while I drink a lot of water, some coffee and at least one bottle of quine water. The quine water helps with cramps, I also take potassium each day because of my heart.
The only reason I have sort of logged my urine output, I wanted to know how much I pee in a day. I average about 3500 ml each day total. If I get to 4000 ml that is over a gallon of urine. I am sure I drink almost that amount of water, coffee and tonic water.
I have had my catheter in for 4 weeks today and I will change it on Sunday and start over with a new catheter for the next 4 weeks. It is nice not to have to get up a couple times a night to pee before I started using a catheter. My urologist doesn't really like catheters so to speak because when I asked him about catheters to control my overactive bladder, he made a face of disapproval.
I have come to enjoy having a catheter in me which saves me from peeing my pants.
