Ideally, I try to get between eight and ten hours of sleep a night. Nine hours is my golden number. However, in the last several months I tend to get less than that, and lately I usually get between 5-6 hours. When I can't sleep I generally don't do anything. Getting up, or reading, or especially getting in front of a phone/computer screen just tends to wake me up. I generally just try to relax and get sleepy as best I can, and if I can't after too many hours I just get up. Sometimes I will try a mindfulness practice from YouTube if I am really desperate, but that's not something I do regularly when I have insomnia.
