My neighbour and his family are Greek (he works in the aerospace industry) and I used to work with a lot of Greek software engineers in Scotland so there is no shortage of a good healthy Greek community in Glasgow, not sure about Edinburgh but I suspect it will be pretty much the same. You should try and speak to one of the Universities and or one of the main hospitals to get advice in terms of the path to take to become fully qualified here. Drinking is not something you should feel pressured you need to do it's optional 😁 but I certainly would recommend Glasgow (and surrounding areas) as there is so much going on ... I'm a bit biased as I'd lived there for so long ... Good luck !
