Did you find out what it was. I have the same thing only it's every Friday after spending 4 hrs or so playing poker with iffy ppl and rarely otherwise. By iffy i mean sone smoked meth and I made them mad and one day I start feeling this poisoning. I'm convinced these guys are somehow poisoning me by air or touch and it's not a medical issue. I'm pretty sure it's killing muscles like the brain! Killing the brain and lowering iq is like slow murder! I'm no longer sharp at 28 I'm so mad, To think some body has this power over me makes me so mad I never understood anger like this! My life is over after years of this my family's convinced i should be in the loony ben. Please help. My gut says meth heads know exactly whats up. A good undercover cop might figure it out. Curezone321 is my tag. God help us please, show us the answer.
