insomnia
"Zolpidem (Ambien) plus melatonin didn't work very well. I had pain from various conditions, and 5-10 mg of hydrocodone (Norco) helped with the pain, but I don't want to be on narcotics the rest of my life. I tried GABA to help out, at the advice of my sleep doctor. At 600 mg each night, the GABA had no effect at all, so I discontinued usage. Now, however, another doctor has said maybe my dose should be higher, so I've taken 1200 mg each night. Very strong effect at that level and I slept 9 1/2 hours! However, it took a while before it had any effect, and it left me groggy and dizzy the next morning. Next, I'm going to take 1200 mg at 7 pm instead of 9pm.

I suspect that after a few weeks at this dosage, I'm going to become accustomed to it."
