I am on day 7 of my first covid infection. Feeling mostly better but still having a lot of GI stuff and for the last day and half have also had this strange, hard to describe feeling.

When I take Nyquil, dextromethorphan, or melatonin, I get this strange kind of "cotton wool" feeling my head, plus vague/nausea unrest in my stomach and, in fact, my whole body feels a bit off. I don't necessarily feel tired, in fact my thinking is quite clear. Anyway, this uncomfortable feeling woke me up after a few hours of sleep tonight.

Also, yesterday, and right now, I've had the oddest sensation in my scalp. "Tingling" isn't exactly the right word for it, but it's as close as I can get it. Also "headache," doesn't really describe the weird feeling of tension/pressure I feel either. None of it is painful or very intense, but it is... There..

Anyone else experience anything similar? How long until it went away?

Also, I haven't slept through the night since I got covid. I'm supposed to go back to work on Wednesday, and I don't want to go exhausted and then be worse. Any tips for sleeping???

Edit: 3x vaxxed with Moderna. Booster was in January.
