<human>: Thanks for reading! My boyfriend and I will be headed out (from the US) for about the second half of October. We're flying into Dublin and out of Barcelona. We are definitely hitting England, Scotland and France, and other areas that aren't set in stone yet are Germany, Switzerland, the Netherlands, and possibly travel through some other places like Belgium/Austria/Italy on train or something to get between those areas; we aren't sure exactly yet.

So here's my main question: does anyone know of a good resource about rules for prescription drugs for these countries? I have read that you should carry a doctor's note or prescription for all the drugs you are using, so we will have that, but I just want to be sure we don't run into issues. The main one I'm worried about is ritalin. The other two we will probably be carrying are just generic zoloft and xanax; not sure if xanax will give any trouble.

Finally, any advice on what to expect weather-wise would be appreciated. I've done some research but mostly just found things like "it varies a lot". We will definitely be bringing raincoats and layers to wear...should I even bother with T-shirts/shorts or is late October too late for that? Maybe just one set for Spain? We're trying to pack light and only bring one big backpack and two carry-ons.

Can you provide a brief overview of the text?
<bot>: Should I expect issues carrying ritalin/xanax in Europe/UK? Where can I find out? How chilly/warm will it be in mid-late October?
