drinking (too much?) water in a day

145lb 5’4” 23FTM dx of type 1 diabetes, hEDS, MCAS, orthostatic intolerance, FND, fibromyalgia and post-covid syndrome. currently being evaluated for HHT (hereditary hemorrhagic telangiectasia). i take insulin, testosterone cypionate, duloxetine, lamotrigine, cetirizine, and PRN lorazepam. occasionally drink, smoke marijuana and tobacco regularly (2-4 packs a week, probably 1-3 grams of marijuana a week) I’ve been recommended by cardiology and my primary care to increase fluid and salt intake to help with some of my issues, but I’m wondering if the amount of water I’m drinking is problematic or indicative of something. I’m fairly used to being a sub-optimal level of functioning due to symptoms now and it’s definitely tied in part to water intake, but “feeling normal” for me usually takes between 120-180oz of water daily. I’ve heard from some people that this is abnormal and maybe an issue, but I don’t know if it’s tied to one of my diagnoses or if something else could cause it based on what other people are saying. I’m not terribly active, I walk a lot and live in a public transit-heavy city because I don’t drive, but I’m not currently working and don’t exercise much beyond PT exercises (very small, muscle conditioning movement) and errands.
