How long are the side effects \"the zapping\" going to last? I have to work or I will not be able to live; the zapping is making it very difficult to work. All I want to know is how long this \"zapping\" is going to last? Every few seconds I get this real quick, \"zap, zap, zap.\" feeling in my brain and it is driving me crazy let along significantly decreasing my productivity at work. I\'m thinking I might loose my job if it doesn\'t quit soon. How long is this zapping going to last?
