Yes, it's a good thing you stopped taking the liquid melatonin; I'll bet it was a little scary having that dizzy spell.
I'm trying to stay away from sleeping pills and other prescription drugs, so I might try taking something else for awhile for sleep,too. I was taking a combination over-the-counter pill for awhile, that contained valerian root. I may try that again, in place of the melatonin. A change might be good!
I'm glad the Moringa is working so well for you. It really does seem to work to quiet tinnitus, and I think it has been helping me with energy level (adrenals) and keeping blood pressure lower, too. Lots of nice side bonuses!
