So I've read many posts about how antipsychotics block or put a serious dent in "feeling" an amphetamine in terms of euphoria, the rush, cognitive benefits, etc. However, at least in my case, it seems as though it enhances the amph effect, definitely in terms of cognitive, and I get that speedy feeling as well. Only problem is that it seems to not last as long, and after a while, the regular doses aren't as effective. Does anyone have any explanation for this? My theory was that zyprexa "refreshes" the dopamine receptors, keeping them from getting shot from extended amph use. If so, could it be used periodically as sort of a reboot? I especially notice the effects if I haven't taken the zyprexa in a while. Any ideas folks?
