how do you diagnose visine poisoning? I witnessed the supervisor at work poisoning another employee. soon after that I started having strange symptoms. in a two year period I had no less than 21 visits to doctors. normally I have low to normal bp. in that 2 year period my bp ranged from 120/80 which I believe the supervisor was on vacation. in 21 visits this was the only time it was normal to a high of 154/100. I walked of the job after I realized I was being poisoned. I could barely function. extreme mental and physical exhaustion. since then my bp is back to normal. in that 2 year period I was diagnosed with hydrocephalus.
