hey. just registered but I've read some stuff on this site before. I used the search feature to try to find an answer to my question, but the threads I found didn't specify whether they were talking about Xanax XR or IR. What I want to know is: How much IR do you need to get high? How much XR do you need to get high? Which is better? Its been awhile since I've had Xanax. Thanks! If I am mistaken, and this has been covered before, please link me.
