Last night i prepared myself to die but it went wrong. Do not waste your time with lithopone. I followed the instructions perfectly in a small sealed box room.I laid down waiting and waiting for 6 hours, there was the smell of rotten eggs and my eyes started to sting and i coughed a little, but that was it. No knock out….nothing. I was so happy getting everything ready and today i’m a failure again. I used 2225 g of lithopone and 10 bottles of 75ml hcl. I stirred the stuff for hours waiting and waiting. Really need to find another method of catching the bus.
