Is there a way to keep your game sharp for six months or more without going out into the field?

I'm in a bit of a predicament. I made the decision two months ago after breaking up with my ex and moving out of her apartment that I was going to stop being an AFC and dedicate myself to being an aspiring PUA. I've learned a lot and met a lot of new people along the way, but now my number is up and Uncle Sam has other plans for me.

It looks like my access to a computer, or even Seddit, during this time will be somewhat limited. From personal experience, are there any of you out there that have been able to keep your PU skills sharp while doing nothing but keyboard jockeying and reading theory?

Here's the other situation. I get leave about six months in and I want to go somewhere to dust off the cobwebs. I've thought about both Sweden and Tokyo, but are there any other places that you might recommend?

Thanks in advance for the help!
