My five cent:
I would prefer beer to chamomile tea all the time and if you go to your local drugstore you should find a bath that says "relaxing, calming down" or something. If you first have that bath- rather hot- plus a beer afterwards (I think 3 would be too much if the size is a pint ) you should sleep rather well.

Make sure Mr. Bear gets a bed of his own or he'll have to go to hospital after Cinder and Smoke introduced themselves
