I've been getting this, too. I've always had issues with, shall we say, chronically "turned on headlights," so I guess it doesn't surprise me. I just want to get it figured out whether it's due to thrush right now or just straight-up Raynaud's Syndrome. I hope the latter! i got some B-6 vitamins, so we'll see if that helps. I don't think it's bad enough (yet) for me to give up coffee, though... that would be a sad day, indeed. For everyone around me ;-)
