motion sickness
"I've taking dramamine a couple of times with good results however the other day I took it and it was a disaster.  I usually experience agitation and dizziness while being a passenger in a car and it usually dulls it but, this time... it made my symptoms substantially worst I developed sensitivity to light , sound , and even temperature felt more intense and that was in addition to the agitation and dizziness.  Please use with caution."
