I survived after being discovered by police. No permanent damage that I'm aware of. I had a persistent tingling in my shoulder that started after taking the SN and would come and go for a day here and there, weeks after. It's a miraculous coincidence the timing involved; first responders giving me methyl blue to treat me coming out unscathed, but handcuffed to a hospital bed.
No pain, either. I'll post something more comprehensive later.
