Have you tried other antioxidants as well, like high dose melatonin (10-30mg), vitamins C & E, alpha lipoic acid, anthracyanins (the red/purple stuff in fruits)?
Hi
@Learner1 - thanks for the suggestions - I've recently increased my melatonin to 9 mg (3 x 3 mg. caps), have been taking vitamin C and E and alpha lipoic acid for years and recently added in a pomegranate supplement.
Also, I take both taurine and glycine before bed which might account for the high levels. I recently stopped the taurine because it seemed to be contributing to my insomnia and now take it in the morning.
I have been taking ornithine - it didn't seem to make any difference. I don't think I have high ammonia at night. And citrulline unfortunately raises my blood pressure! It was supposed to the do the opposite.
I use a progesterone cream, and my levels are okay.
I still think my thyroid is involved. I just added in l-carnitine and went to sleep more quickly last night. l-carnitine is supposed to block T3 and T4 entry into the cell nuclei.
Effects of carnitine on thyroid hormone action - PubMed (nih.gov) I first tried acelty-l-carnitine but that seemed to make the insomnia worse (!)
And I've been off my thyroid med for a few weeks now - I can't remember how long it's been - 3 weeks? (I'm out of town and don't have my notebook here) anyways, I've never gone this long without it without negative effects.
I've been taking 5 mg liquid doxepin at night for about 5 days - I don't like taking it, it leaves me woozy but I'm at my son's house and had to take something for sleep, I hope to stop it once I get home - if it has been my thyroid, hopefully it's calming down!
