The acceptable face of electro shock therapy!
Technically known as “Trans Cranial Direct Stimulation” and recommended for sufferers of depression.
However on reading, it mentioned it may improve/reset sleep patterns. There seemed very little adverse outcomes advice, so after discussing with my Parkinsons nurse I gave it a try.
No “silver bullet”, but I did start sleeping if not longer, then “better” (deeper, more restful); your experience may vary!
