Been taking the one that has gel in it( forgot brand) don't like the gel. It doesn't last 72 hours at best last maybe 48. It's huge and uncomfortable to wear. Just switched to a regular patch brand name Alvogen. Really would like some information on the brand ,on sticking power and if it may or may not last 72 hours. Only thing I do know about this brand is it has 5.32 mgs total medicine. Which is pretty good compared to other brands.
