Hi,
How I dealt with the insomnia was by waking earlier (find something productive to do).
You eventually get used to it, but I did use some L- Tryptophan each night for a little while.
Now when I cycle in and out of keto phases, I only have 1 or 2 nights of insomnia.
If I had more in a row, use some L-Tryptophan for a while…
As far as I know, keto folk dont need as much sleep anyway
