Fear of spiders, heights, flying, whatever? The first thing you should try is a simple process of tapping on acupuncture meridians.

For most emotional problems EFT is the first option of choice as it takes only a few minutes and has no negative side effects. It it works, great! If not, try something else. (Actually, if you persist with EFT and/or get some help it will always offer some benefit.)
Significant research material is available for EFT and you can download a manual for free.
