Everyone is different. My sister had it when she was 16 (1984) and basically slept most of the summer. I know others that have had it and were only really affected for 2-4 weeks. My other sister and I never had it.
I have a friend who had it at 35, but she didn't have "time" to sleep so she just took a couple of weeks off and then came back to work full time. It took her a little longer to recover, but she did.
