What is the best time to zap?
Any time is fine. I usually strap on a unit whenever I’m in front of the TV for any length of time or have an hour or so that I’m going to be sitting relatively still. Zap with foot pads first thing in the morning or put the foot pads under a desk at your computer. If I’m too busy during the day, I sometimes grab a zapper as I go to sleep. The auto-timing units are great for that since it times the complete cycle for you, all you do is hit the start button. With the non-timed units make sure you use them for the recommended 7-20-7-20-7 minute cycle or use continuously at least an hour. Find a way that works well for you.
