Question about upswing

[Nickerbocker]

This might be the stupidest question ever asked. I dunno. Anyways I went through a helacious downswing to the tune of 10 buyins a bit ago. From what I can tell now it's starting to come back up(you know, flopping sets every other hand, AA/KK every 40 hands, boats filling up against straights etc.) In other words im running pretty hot right now. So i've got 2 questions I guess. 1) how long can I expect this to last and 2) I satellited into a pretty big tourney, the biggest ive ever been in, so is there any notion to "saving" my upswing for the tourney because Im playing microstakes right now and I dont want to be running super hot at the micros and then go cold for the tourney. Anyone?
