One more thing if I may Eva, should I take the tab in the hotel room, wait to see how strong it is, then go to the museum/concert? Or should I just take it outside and let it work its magic while I'm in there? I am unsure! I have been in public on acid before but only for a couple hours and it was not too busy. In this case it will be for most of the trip and in a busy city I don't live in. I've never freaked out on acid but what do you think is the best course of action?
