I don't have a lot of patience... It basically depends on the game. A well designed and interesting game will make me more reluctant to use a walkthrough trying not to ruin the game experience. That said I almost always will use a walkthrough...even if it is only for one or two puzzles for a game.
There are cases where the game can't keep my interest and I simply use the walkthrough to see the story.
And there are cases where I use a walkthrough for a puzzle only to find out it has a really stupid solution, that ruins my trust to the game designers and the moment I get stuck again I resort immediately to a walkthrough thinking the puzzle could be equally stupid and I should waste my time figuring it out.
