Some thoughts on zeitnot:
In general, you will never be able to play always the best move throughout a game unless your opposition is very weak. A chess game is a struggle and it doesn't help to play a long sequence of best moves and in zeitnot blunder the game away with one move.
Some time ago I had the same problem and searched the web for tips, but there was only little I found and those guys often copied from each other. I think the first thing is to do some self analysis why you get in zeitnot.
Reasons for getting into zeitnot:

Lack of confidence /Afraid to make mistakes. One of my students always gets in heavy zeitnot. He is calculating all variations several times to be sure he didn't miss something and he overestimates the strength of the opponents threats.

Lack of physical fitness. This will let you get tired the longer the game runs and badly influence your concentration and ability to calculate.

A strange fascination for a combination which almost works. I experienced this once against an IM where I could have sacrificed the queen for two minors and some pawns. I decided not to do it, but he played an indifferent move and after that I began checking the sac again... The end of the story was I blundered away a fully equal position after saccing a piece (correctly!) in zeitnot.

Self discipline (this might be connected to the point above). Kotov says you may only calculate a variation once. Some players hop between variations, often because they cannot decide which one to chose.

Lack of practice. Playing only a low amount of serious games.
Tips how not to get into zeitnot (or simply to save time?!):

When your opponent thinks, try to work out your general, long term plan and strategy, so when it's your move you can think of how to achieve your goals.

Play openings you studied well and know the general middlegame ideas.

Knowledge of (at least basic) endgames will help you to decide when to go into the endgame and if it is a win, draw or loss without calculating.

Knowledge of strategical ideas (pattern recognition?! btw a GM knows several thousand) helps to find the right move. Zibbit's video series on that is nice, but there are also some good books on that, one of my favorites is by Bronznik and Terekhin 'Techniques of Positional Play: 45 Practical Methods to Gain the Upper Hand in Chess' english version will be published in Octobre 2013.

Develop a feeling for critical moments. I am not sure how to train this. Maybe by writing down the used time for each move and plotting this together with the evaluation of the position versus the moves. I remember Bronstein has suggested something like this.

Do solitaire, guess the move or whatever you might want to call it. Take a database, book, magazine with games that contain high quality annotations. Get a database with the games without annotations and either analyze the games (write it down!) and compare. Or try to guess the moves played in the game using a fixed time per move or for the full game. This can help making decisions under time pressure.
I can really recommend 'chess hero' to do this, because it saves the history and after the game (or much later) you can check which moves you didn't find to see your weaknesses.

Finally one that was given in the web. Playing some games with shorter time to get used to playing quicker. I'm not sure about that.
