Worked the night shift as a nurse in Surgical and Trauma ICU, 7P-7A for a few years. Yes, the pay was better and as

but I never managed to sleep much during the day. And it isn't truly 7P-7A. Add in drive time and the fact that many times the relief nurse would come in 15-20 minutes late and it mostly ended up being 6P-8:30/9A. One morning on the drive home, I fell asleep at a stop light. The driver behind me honked and woke me up when the light turned green. Scary.
When a day shift position opened, I jumped on it. Never wanted to work nights again. However, after six years of ICU, I transferred to OR day shift. Night shift had much less staff so on holidays and weekends, I would volunteer to work that shift because the pay was so very much higher.
There were some, however, who worked nights for years and loved it. Different strokes...
