<human>: I am a 19 year old girl from Australia. I have auto-immune pancreatitis which means I am not allowed to drink alcohol, period.

I have ALWAYS wanted to go to Europe. I hear from everyone my age that contiki's are amazing/you meet so many new friends/fun/drunk yada yada. 

That's great, except as someone who can't drink and is in a long-term relationship, I wonder if that takes the shine off of a contiki?
I know that for a lot of people my age, being drunk and hooking up is one of the funnest things they can do.. but for me that is the opposite of what I would look for in travelling. I've always had the itch to travel as I am a big history/culture lover. The drinking/shagging side has no appeal for me (I swear I'm not that boring).
But I don't want to be a massive buzz kill for all the other people on the tour.

At the present time, it looks like I will be going with my boyfriend and two other friends of ours.

Bearing this in mind, I was wondering if you would still recommend a contiki? I mainly ask because I have been told that it is a great way to see Europe as a first-time traveller, and then figure out where you want to delve further!

Can you condense the text into a few key points?
