Ha! Well seeing as I'm in work and the bears are in a drawer in south Manchester, it'd be difficult on more than one front. :D
Wouldn't want to build tolerance either - seeing as I've not taken acid since the end of the summer I want to really savour the reunion. I found a couple of comments from A4B actually, and I trust him on these matters.
I suppose if I'm around mates and the atmosphere's good (which it will be, despite the fact the most evil band in the world will be playing) then dropping two wouldn't cause any problems in a gig environment. It won't be like I'm sitting in my room listening to Swans all day, which caused me to have an experience last year that was a little too intensely introspective.
