I think it has truely fucked up my hands and feet. I've been getting weird cramps in them for a few weeks now. For those who have stopped taking after periods of heavy use, and experienced similar side effects - if it has gone away at all; how long did it take?
This is probably due to the lingering vasoconstriction that I have seen people mention on here.
Not sure how serious it is to still have it weeks after discontinuing use and not too sure how to combat it... but I would just suggest what I always do for minimising vasoconstriction while on the drug. That is; keep well hydrated (ie: drink more fluids) and keep yourself (ie: your extremities) warm.
