I've not been a large fan of naps for many years as they used to make me feel somewhat sickened upon awakening from such.
However, having taken up some active WILD training I took my first nap in a long time yesterday during the day and noticed something curious.

I was falling asleep nearly instantly after relaxing for no more than half a minute while sitting in a chair (but a comfortable large one at that; throne-like allowing to put my head back at ease and so on). What I mean by falling asleep is rather that I was nearly losing awareness within a minute or so compared to the usual way of falling asleep in bed lying down horizontally and that taking quite some time.

So my question is: does anyone else find napping while sitting easier/swifter than when lying down?

Specifically I'm interested in using naps for WILDing as such swift sleep onset seems to be quite favourable for it.
Any input would be appreciated.
