If any of you think of heading to Spain for a few months and are like us and can only get 3 months supply at once of your own doctor do not worry. One of Lynda's drug is Methotrexate which I believe is a controlled drug and we have just walked into the local Pharmacy and picked it up with no questions asked.
I believe this is the norm in Spain for any of your medication but as a precaution bring your pescription copy with you and of course you have to pay but it appears reasonably cheap.
I believe in France it is much more difficult and you would have to see a doctor first. Not sure about Portugal but will find out after Christmas
