You may be getting high levels of mold/yeast toxins in food and supplements. These are neurotoxins and aflatoxin is similar to LSD. I take high doses of Vit C and have more restful nights.
I have been able to keep my body slightly alkaline by balancing my foods. Search for 'acid/alkaline ash' or acid/alkaline forming foods. Testing the saliva with a pH strip is helpful.
