Never tried it, never wanted to try it, never felt like trying it...... Your mind's too valuable a piece of kit to risk damaging it in exchange for a doubtful enhancement of the imagination. That goes for drink as well. Been there and don't do it any more. Sorry if I seem stolid or old fashioned, but I've seen some of the results and it ain't worth it.... Most people can get all the enhanced enjoyment they need by educating the mind to develop.

Down off the soapbox........
