Virtually every evening, around 9PM, I have a sudden energy crash that's nothing like normal getting progressively sleepy. Instead, most of my energy suddenly drains from me, my legs feel weak & uncoordinated, and I feel massively fatigued. Within 1/2-hour, even if I get right in bed, my body starts feeling "needles & pins" or acheyness in my arms & legs, and my mind starts racing and going into serious anxiety. With all that going on, falling asleep is near impossible, so the symptoms just build through the night.
Some people the symptoms seemed similar to a low-blood-sugar attack, but since they hit regularly every night, often right after finishing a large dinner meal, I'm sure it's not low blood sugar.
I have found no cause and no cure, and all doctors seem clueless. Herbs & supplements like Melatonin, Valerian, Kava etc. do not help; the only thing that works to "turn off" the symptoms and relax into sleep is taking Klonopin (a benzodiazepine like Xanax or Valium.) But I've only taken it intermittently, and want to avoid regular doses, because it's addictive.
Anyone out there recognize these symptoms and can help me figure this out?
