Has anyone been worked up before bed, mine was worrying about a really bad headache. I couldn't sleep and my body felt out of whack, head racing, felt like internal tremors in my legs (like jelly)  felt off balance, discordinated  and scared. Heart rate wasn't up too much may have been the codine I took. Leaving you feel really on edge? Lasted all night till this morning now I'm left feeling really down.

Is this a common anxiety factor??
