Scrubadub, Shawn, you guys are probably right. I may be overdoing it. But I had a persistant recurring bad taste and NEEDED to do it every day for a while last week. So I've already done it a LOT, and I'm going to get a new atomizer as soon as you've got them up, so this one makes a good test bed. I'll keep doing it frequently, like whenever I change a cartridge, and we'll see how it goes.
