Let's say you are high on speed and you start getting tension right in the middle of the chest, where rib cage start to form, ya know, right below the base of the neck. You just start rubbing it and rubbing it, to the point whenre it is fucken inflamed and burns (skin on the outside) a little, very uncomfortable. Would taking some XANAX (ALPRAZOLAM) help to relax a little and maybe take away some tension? And the main question, is it safe to take XANAX or benzos in general when tweaking? Not on the comedown from speed or at the baseline, but tweaking majorly....any risks of heart attack?
