Does ketotifen brain fog eventually go away

started ketotifen 10 days ago, 1mg at night. first few days were ok but day 4-5 hit hard, completely fogged out. can’t focus on measurements at work, everything feels like moving through water. machinist work doesn’t tolerate that kinda slowness.

doc said it’s normal and should pass in a few wks. but i’m wondering if it actually does. anyone else get that zombie feeling starting it? did it clear up, or did you have to drop the dose?

might switch to cromolyn if it stays like this, but figured i should ask first. how long till your head cleared?
