I had severe insomnia when I had Covid19 back in December 2020. I was sick for a month and had strange sleep patterns. I would "half-sleep" and then have the same dream every time I started to drift to sleep. I tried 9mg Melatonin but that didn't really help.
When I returned to work at week 4, I asked my primary for a sleep aid. I was prescribed an old anti-depressant that is now used for sleep. It is Doxepin and I take 3mg 30 minutes before bed; 6mg was too strong. The 3mg does cause me to get drowsy at bedtime and does not leave me feeling sleepy in the morning.
I wanted to get off the prescription med, Doxepin, and tried a 30mg CBD gummy with good sleep until it plateaued and didn't keep me sound sleep, - anymore (I only took a half gummy because it caused nausea).
I was told by a friend to try Gaia Herbal supplement for insomnia. I will be trying that soon to take a break from prescription Doxepin.
Hope this was helpful - Kim
