and by the way...

no one can function when sleep is badly affected. It's top priority especially for me. I find my days after lack of sleep filled with brain fog, what I call "brick brain" (Mark calls it mud brain I think) and terrible vertigo.

You could in your own time start looking into sleep hygiene changes. Everything is individual, but maybe you would start to feel a lot better as a whole if you could just learn to calm your mind without drugs right now.
