I was prescribed xanax xr but something mixed up and i was taking normal xanax

As far as I know the normal one is supposed to be stronger since it releases in a shorter time but because of this last less than the xr

I was feeling lots of side effects and we discovered i was taking the wrong one so I'm starting to take the xr in a few days, I'm worried it will make me feel worse though

I felt the effects and they were pretty strong at first but started going away after 12ish hours and lasted more than 24 hours without the extended release one so this one is going to make me feel even worse, i suppose?

Does anyone know anything about this?
