Hyperhidrosis started for me at age 10. I reluctantly bought a set of drionics and researched them online. I found that if you put a drop or two of apple cider vinager into them and use warm water, they work! And while a bit costly to keep purchasing batteries, they have changed my life. They are very painful to use at first. I used them for 1/2 hour on my hands as painful as I could stand, then turned them and used them another 1/2 hour on my hands. I did the same with my feet, which wasn't so painful. After 6 days I was disappointed, as I was still dripping sweat, but by day 7 of treatments, amazingly my hands and feet became nearly dry! It was incredible. If your daughter can stick with it, I encourage using the drionics. I think you can return them within a certain amount of time if they don't work for you...but persistance is the key. Remember that when the units are painful at first. You can do a search for drionics through google, or maybe this will work for you: http://www.drionic.com
