jenkem screen shake lasts forever

[magic mountain]

Checked this out, the jenkem effect can build up to very high levels and depletes very slowly. You can make it go away five times faster by resting but it still lasts a long time if you had a huge dose. It will eventually go away even while standing after anywhere from 3 seconds to 50 minutes (yep).

I'll take a look at changing the way jenkem works a little bit.
