if you'd been tanning meth,maybe no too much.if you're straight and have never done it before,well i dont know exactly how to describe it other than real fucking good,you'll maybe spew the first few times,even that'll feel good though,weirdly.
oh yeah,when i used to get asked this years ago i'd always answer "you're in yer flat,you're high as hell,some cunts attacking you're door with an axe,and you just cant be botherd caring"ie - beyond chilled out
It's just wrong... It's the feeling you get when you find a lost wallet or set of car keys when you really need them x 1000. It's also as addictive as any other way you might get it in to your system.
