Dehydration

Hey everyone, I'm new here but I've been suspecting I have this disease for a few years now. I have always had UTIs from a young age, but sometimes I would get these flare ups that weren't a UTI but felt like one. I have been able to sus out the main trigger being dehydration.

I usually drink nearly a gallon a day, but I find it harder to keep that up on weekends or my days off work. Today I barely had three bottles of water, and I'm paying the price for sure. I'm having a lot of discomfort, and currently have a heating pad on my vagina to help ease that a bit. I guess my question is, does anyone else notice this as a trigger? It's the only thing I can pinpoint for what's happening. Also, does anyone have any ideas of what I can do to ease the pain?

Thank you in advance!
