You should follow the instructions with your machine but the usual treatment schedule is to have seven sessions of treatment on days 1, 2, 4, 7 , 10, 15 and 22.
The treatment takes 20 minutes for the hands and 30 minutes for the feet.
That should bring the sweating under control. Maintenance treatments are then required as soon as you start to feel the sweating return which can be anything from a few days to a few weeks.
