Blurry vision and physical problems from not drinking water? I know each person is different, but I really doubt it's that. Yes, I'm speaking from experience.Someone on Kirsche's Discord was wondering if it's side effects from long term low grade dehydration. Girl probably doesn't drink nearly enough water. This very well be the manifestation of that.
It's likely from a variety of issues. Trying to pinpoint the exact cause-if my understanding of Pippa is to be believed-is going to be pretty damn difficult.
