Let the tape record silence for about 20 minutes then start turning the switches back on. Turning the switches back on is very important, especially when just starting out. DO NOT just jump up. Roll over on your side and slowly sit up. You may be dizzy or light headed.

Some have trouble when they first start. I wanted to cry. It took me forever to learn. Now I don't have any problem. I have taught others and led more than one oral trip with a couple of us taking off together.
