Uncertain. I was in bed from 9.50pm until 9.50am. I might have got to sleep around 2-3am until maybe 7-8am. Garmin is currently down, so I can't verify my sleep or overnight heart rate data, but from what I glimpsed it looked like I might have got 4-5 hours, which would probably be the most sleep I had in 4 days. I have to brute force it though. Don't feel 100% at all but at least have the day mostly off and if yesterday I felt at 20-30%, maybe today I feel 30-45% which is a slight improvement, on the other hand haven't had any anxiety or blood pressure spikes as yet, so maybe it's more of an improvement if I take that into account. Still feel a bit nauseous, but my body is going through a lot. Still don't feel optimistic or confident of feeling fully better, but am not quite in despair either.
