i would tell you from first hand
if you are over 60 or have some health problems
DONT use it
i spend 2 days in bed ,
this works different than the other 2 , and is not fun.
may be better in the long run down the road, but it dont use same way to treat, this is long term , may work or many things, but its not a nice thing up front
i am fine after 3 days , but was not sure the next 12hrs if i would be typing this
just some helpful info
