I just want to throw a couple tricks out there for you folks.

Something my mom showed me a long time ago for relieving anxiety attacks during the night seems to work really well. Every one has a smell that reminds them of their childhood. My mom will keep baby powder next to her bed, and I keep a little container of Carmex to smell, and sure enough it really relaxes me. I no longer have anxiety attacks, but the trick does still work very well.

Also, when I WBTB, I'll always make a cup of hot apple cider to calm me down. Both these tricks are very effective. Give 'em a try.
