I took a pill, now I feel better!

There is absolutely nothing in the above statement that is not spot on correct. Well said Tim. If you have an overheating problem, look elsewhere such as ignition timing or poor cooling system.
If you do most of your driving in a cold part of the world, yes I would recommend the use of a thermostat to bring the engine up to operating temp more quickly. I live in the tropics and do not see a need use a thermostat as my engine reaches operating temp very quickly but does not overheat because the cooling system is in good condition.
Now, where did I put my Pill bottle.
