I started doing epsom salt baths with lavender oil during my last long fast. It helped so much I’ve kept it as part of my bedtime routine. I don’t take any sleep aids.
While fasting I woke up much earlier but I fell asleep easier than on previous fasts and felt rested when I woke up.
These magnesium glycinate sleep capsules are awesome for fasting insomnia! Also has melatonin, GABA (great for stress/anxiety ), L-Theanine and 5htp. Also, no grogginess the next day!! https://www.amazon.com/Reset-Electrolyte-Electrolytes-Melatonin-L-Theanine/dp/B094RFF6RC/ref=sr_1_5?crid=1X0N702G7LNI2&keywords=reset+electrolytes&qid=1672843231&sprefix=Reset%2Caps%2C142&sr=8-5
Reddit through insomnia and cry when still awake and at work. I just distract myself, I’ll get just a couple hours for 5 days in a row, for me it’s just an unavoidable part of the long term fast experience.
