Water. Sounds basic. We need it. I don't drink enough of it. I'm supposed to drink 63 ounces per day. This also means I need 63 trips to the bathroom. That's my problem with drinking enough water. I have to pee all the darn time!
Does working up to the needed amount help? Sort of like conditioning the bladder.
I'm going to try 32 ounces today and see if I can gradually work my way up to 63. If you need me, I'm pretty sure you can guess where to find me.
