Interesting Clutch Problem

[RanciD]

This didn't start happening to a little after I adjusted my clutch so I figure that might have caused it because I didn't bleed or anything afterwards (I just searched on here for how to do it and it didn't mention anything about that). I loosened the lock nut and set the engagement point closer to the floor so it catches sooner while letting it out. This is the way I want it. It was fine for a little while after this and then I started getting this strange problem..

When I first get in the car after it's been in the garage all night the clutch catches pretty close to the floor like I want it. As I drive and keep pushing in the clutch to shift the engagement point slowly works its way out until eventually it doesn't catch until the pedal is pretty much all the way out. My worry is that if I drive it like this after a while the clutch won't even fully engage and just start slipping. If I leave the car for more than a few minutes and come back the clutch will again catch close to the floor and the process repeats itself. To me this sounds like it could be some type of problem with the damper or a combination of fluid and the damper?

I can get the car on a lift pretty much whenever so before I do that I figured I'd ask the professionals here for some advice as to what I should be checking for or doing. Thanks for any help!
