Thanks mate for the reply!would like to know the big differences in life i will face.how did you feel when you moved from scotland to poland,was it hard in the beginning?
Yes, but that was more just because the missus left me 4 days into my stay. This was 2 days after starting a job and with only 2 weeks left on the flat. So that made things a struggle just because I didn't know anyone. I think the best advice I can give is come over with plenty of cash (enough to last you at least 2 months VERY comfortably) and get yourself out with various expats and gain as many contacts as possible...it will make your life a lot easier the more people you know. I know there is the whole thing of "ooo, you come to another country and hang about with other expats" thing, but for the start it is very handy to get yourself some grounding.
The language could be a struggle depending where you stay. A lot of shops in smaller neighbourhoods don't speak english and you have to ask for things over the counter. So try and get your girlfriend to teach you as much as possible before you come.
Emmm...other than that it's all good. Great city, great beer and great people. You will love it.
