Q. Thank you for your website! I am so glad that I found it this morning. I suffer from insomnia and I wondered why. As it turns out I have been overstimulated by taking daily Acetyl L-carnitine (a whopping 750 mg) plus L-Carnosine 500 mg plus R Lipoic Acid 200 mg. I think I will stop taking any supplement for a week, maybe two.
