coping with not surfing for a while...

i live in wales and surf pretty much whenever theres swell, which is quite often....am proficient, have been surfing for around 3years. get out back, noseride, dodgy cutbacks and happy in overhead waves. the reason i am on this site is to ask about experience/tips about not surfing for a while. this is a major factor in my life as im moving to the city to study. i will have gaps of surfing (a week here and there) when im home (month for christmas ) but all in all is surfing like riding a bike where you just get back into the hang of it or do you lose it? i love surfing and have a real passion for it but also want to study - torn between two! ive been in the city for two days and am already missing it, looking at surf reports just makes it harder. ok any advice would be appreciated,thanks ever so much!!! 
p.s lived away from home last year and didnt surf as much as i used to and thought that my surfing (bizzarely) may have improved slightly!
