Like bird dancer, I’ve not necessarily slept but have stayed in bed for months, only getting up to use the rest room. The most I’ve actually slept I would say is about 18 hours.

The longest with no sleep was my most severe manic episode. I got 2-3 hours of sleep for about 5 months straight (and was functioning on that) and then about 3 days with 20 minute naps, a few more weeks of 2-3 hour nights, then a major crash.
