one thing, is you will still retain the knowledge you had before. so when you go to practice again it may not be so hard this time around. i can tell you from experience a little bit. i was in full swing with it early summer but i stopped for some reason at the end of the summer. i picked it up about 2-3 weeks ago and could start up knowing some techniques already. i have only had 3 ever so far, but it took a lot less time to get my 3rd when i started it back up this time around. its like playing a level in a game for the first time, then after you beat it you come back to it again later and you kinda already know what you are supposed to do and next time you beat it even faster.
