Had a difficult transition to night shift - quite a bit of insomnia this time.

Tried the stairs tonight, and it wasn't working out. Heart felt like a trip-hammer after just two trips up and down, at 150 BPM. Usually takes 6-8 trips to get it that high. So I stopped at 10 and called it good.

10 trips up and down the two flights of stairs
151 BPM avg and 6:45 min.

On a more positive note, the intermittent fasting is going much better than the stairs. Managed to pull off a couple of full 24 hour fasts, followed by eating keto-friendly food (mostly cheese and almonds). The pounds are really dropping off - it's just amazing. Down one pants size already.
