Last time was around the beginning of just last month, actually. I came down with something and while it was the couch I crashed on and not the bed, there was pretty much no way I was able to stay up for long, just didn't have the energy to do anything.
Believe me, I tried. Even sitting up was tiresome after a short period. Wanted to get up to do anything at all? Nope...better get it done quick, or it's not happening.
So yeah. Usually only when I'm sick and just not feeling able to move much is when I'm most likely to just lie there all day. So not that often.
