What does it truly feel like when you finally get a real break from your anxiety? Like, little more anxiety, and finally passed the 'hangover' of your anxiety; what does that feel like?

Do you just feel like you could go for a nap? Does it feel like how movies portray 'stoners'?
I just want to know how your body and mind feels when it finally gets out of that stress response 'loop', even for a little bit.
