Sleeping well the night of cleanse

Hello cleansing community,

How well do you all sleep the night of the cleanse? My natural foods store has the ornithine mixed with another ingredient, not just pure ornithine.
Have you had any experience using melatonin rather than the ornithine for help sleeping on the night of the cleanse? I use melatonin occasionally and wonder if this is just fine to use instead. Or do you think that specific sleep inducer is necessary for working with the cleanse ingredients?

Thank you in advance for your consideration.

Love and light,
Abigail H

P.S. Thanks you so much for the dry sauna comments to my previous question---your input was very helpful, and I've decided that for this first cleanse I 'll stick tight to the "no water after 2pm" directions (but will hydrate if needed).
