online timer running out.. what do you do !?

[cbloom]

Whenever I'm in a really tough situation I take some time to think, but the online timer is really short, and it often runs down and I'm still struggling with the hand. Now I have to act quick or my hand will be killed. Do you guys have any tricks for this situation? If in doubt, fold, call, raise? Usually I'll fold in these spots, but I think I'm giving up a lot of value.
