Magnesium Threonate, Theanine Serene with Relora and Acetyl L-Carnitine.

Will keep taking, along with top ups of Magnesium Citrate and, occasionally, the Good Guru supplement that I mentioned. But, it's definitely those initial three that made and make the difference. Have started making art submissions again. Bless you for your initial post on the subject. Looks like I can have my artist's life back again. Thank you.
