When mine starts going up fast but is going to crash I feel sweaty and hot dizzy nausea weak and shaky and I'll check and catch it going up and just keep checking and suddenly it just drops fast

feeling extremely dizzy, passing out, slurring words, literally feeling high.

I will suddenly feel my mouth in general get very numb and tingling. One episode I had a internal seizure.

Sometimes I feel nothing my service dog will just alert
