I have been snorting heroin every couple of days for about two months now (with larger, two week breaks mixed in), and lately the heroin has mainly been making me feel dizzy, overly hot, with very little euphoria. I never got too much euphoria from heroin, but i definitely expected more than this. What is the best way to maximize euphoria and limit the dizzyness? I only started getting dizzy recently so I don't think it's a tolerance thing.
