pre-performance rituals!

lets start a thread on pre-performance rituals! What do you do before a show to calm your nerves?  What do you do before a show to warm up and stretch?  What do you eat or drink- or do you avoid eating and drinking?  Do you watch any inspirational videos or listen to any particular song or music to pump you up??  Prayers?  Meditation?  Lucky underwear?  :D   I like to include glitter in my makeup!  Glittery makeup and shiney costumes really make me feel like a performer.  I warm up with some yoga and mild stretching.  I remind myself to be prepared to improvise if necessary and have a plan B trick or move if plan A doesn't work out.  I also remind myself to do my best and remember that the audience is on my side (that makes my nervous butterflys flutter away).  I don't eat too much because a full belly makes me fatigued and I allow myself only a half shot of something alcoholic if my nerves are out of control.   Videos of Felix Cane really help get me in the zone. What about you guys?
