For successful zapping it is necessary to take supplements to aid the body in detoxing the die-off.
L-Arginine in the morning [better than coffee for a boost of energy - it washes out the debri]
L-ornithine at bedtime. [helps you get to sleep - it also washes out the debri of die-off]
Vit C and any of the detox herbs would be advisable.
The terminator is very simple to use, but I do not have personal experience with it.
I used the original Super Zapper DeLuxe and had great success with it. I use the bars under my feet. Dr Clark zaps through the feet at all times if possible.
I did purchase the 2004 model but have not opened it yet. I need to get the converter so I can use my program drivers.
IMHO the increased age spots are indicating liver stress. You may want to consider liver cleansing. I have a simple and easy liver cleanse.
