It's a good problem to have, I'd say 2 things, either decide not to let it bother you vote away and let your power drop super low, or use something like busy.org or one of the extensions to give you a slider. (Or buy enough steem to get one, it is pretty low now and maybe even a good investment)
Trying to balance it and restrict your voting is just going to keep the steam coming from your ears... lol.
