iv done it a few times.. yeah...
the first was amazing.. i had some crazy hallucinations that i enjoyed
the others were more weird... i thought i was on a WW2 battlefield too, but i had a gun and i was killing a ton of people. then somebody gutted me with a bayonett and i was holding my guts in. when i came back, i was rolling around on my carpet holding my stomach!
iv made a point not to mess with it anymore...
