How to deal with time-control pressure? I find myself frequently running into time trouble. Even though mentally it feels like I didn't use that much time, when I look at my clock it says otherwise. When this happens I start rushing to try and make up for 'lost time' with blunders soon to follow.

I have an idea of where the time is going -- usually it's when I'm analyzing a critical position and I'm calculating the moves out. Many times I can't seem to find a clear plan to carry out because of time pressure.

Are there any techniques or ideas to try out and practice to help with this problem? What do you guys do to tackle this issue?

Edit: To answer Akavall's comment on when it happens. I certainly don't run into time-pressure in every game -- eg. if my opponent made a big blunder and I'm up in material. Usually it happens when the position is about even. I take too long coming up with a plan and the most accurate candidate move. Other times it happens when I'm in an inferior position trying to size up a defense.
The two main things I do to avoid time trouble are:


I write down the remaining time for each player after every move. This both keeps me very aware of the amount of time I have left, and lets me know how much time I have spent thinking so far on the current move, so I can take appropriate action if I've already been thinking for 5 minutes. I also try to have a few checkpoints; for example, if the first time control is at move 40, I try to have at least half my time left at move 20.
This one is harder: in a non-critical position, I am willing to take less time than I'd like and just make a decent move in 2 minutes instead of spending 10 minutes looking for the best possible move. Of course you don't want to do this when the difference between the best move and second-best move is very large, which you don't know in advance, so you have to use your experience and intuition.
