Yep been there. Took to sugar cubes to a festival, one was for a friend and they decided they didn't want it so I was a bit pissed cos I could have left it in my freezer so instead of letting it crush up and spread in my pocket (was just wrapped in foil) I put the 2 in a drink of vodka and skulled it back.
15 minutes later I said to my mrs that it was probably a bad idea as I was feeling it come on already.
5 minutes later the keys on my iPhone were dancin off the phone and my iPhone turned into an iPad.
Was a very interesting day, time completely stopped. I didn't regret having the 2 in fact I'm a sucker for tripping hard, I just would have liked to be able to save the 2nd for another time as it was the last from the bottle.
Shit happens. Lol
