I'm sure it's just wishful thinking but I have suspected in the last year that my oxybutynin pills have not been consistent in their strength. The only reason I would even question this is because I chew all my medicine except cymbalta. Even my fish oil supplements. Weird,yes,oh well. The majority of the time (mostly) when I put the pill in my mouth it is tingly or something like that. I'm having more incontinence issues and the oxybutynin is not tingling in my mouth with a lot of the pills in this bottle. Any thoughts pretty please.
