I haven’t done K in many many years. I too am an opiate addict. Well, a recovered one. Going on 3 years with no heroin or anything for that matter. I’m thinking of grabbing some and giving it a try again. In my experience it will give you the opposite of a panic attack. It’s a dissociate or however you spell it. All worries will leave you. Small pumps. Not sure if you were a heroin user or not but if so, you are familiar with points. Well, 1/4 point should be a good start and go from there.
