I also take a number of medications, including Topamax
for migraine, blood pressure meds, Celebrex, asthma medication and diabetes medication. However I have had recurring visual disturbances that only happen at night. I get up in the middle of the night - to go to the bathroom - and the bathroom is covered in geometric patterns, like a checkered pattern or little lacework pattern. It's everywhere, the walls, tub, sink, floor. I feel like I'm tripping on something!
