Read a book or browse some websites if you're not comfortable playing more tables. Just make sure you focus when you do play a hand. But this is just a suggestion, not something I have "tried and done". Personally, I play 1/3 of my hands, 3 tables, and 6max (which is a lot faster than full ring) so it's never been a real problem. I do know what you mean however, when I move up a stake and play one table to adjust, it gets frustrating like hell.
