nausea/vomiting
"Patch used for second general anesthesia experience since I vomited after the first time.  I know they also switched me from a gas/IV combo to pure IV sedation, so although I did not vomit this time (yay!) I don't know if I can attribute it to the patch or to the sedation change, but probably both.

Please be aware these patches are NOT meant for long term use- they will have withdrawal effects! If you rebound you will have the very effects you were trying to prevent in the first place.  For my purpose, after surgery, it's worked great.  I wouldn't wear them for weeks at a time."
