I think I have some sort of social anxiety because I sometimes have trouble sleeping the night before having to wake up for a social event. This past Sunday I had a family brunch I had to wake up at 9 am for. Despite waking up at ≤9 am almost every weekday I had a hard time falling asleep. I took the strategy I do on red eye flights and just relaxed, making a big bowl of popcorn ~5 am. Then I managed to get a few hours of sleep. The next day was a minor challenge but I was okay. I also took supplements to support my immune system because I often get a cold when on low sleep. I think it's just like most types of training or anxiety in that I need to expose myself to waking up for early social events through more repetitions incrementally.
