no sleep for 3 weeks

It sounds extreme as I tend to fall asleep at the slightest excuse but are you cat napping without realising?

You must be resting enough to function I guess, but that is a long time without sleeping well.

I'd go mad - I'd lose my sanity - if I went without sleep. And I know this from experience. Many years ago, I went without sleep for 3 days: I lost the plot and became panicky, sweaty, listless. I felt absolutely awful having the sweats and the shakes. I knew then I needed to sleep every night. I cannot function on little or no sleep.

Also, I don't feel guilty anymore when I have a lie-in. I just lie in bed and feel refreshed when I do finally wake up.

I love my sleep and always will.

...and you never drop off during the day or evening?

now in my 4th week.

and still no ill affects
