Mac,
When I first started I did 15 minutes per polarity because the video recommended that and I guess I was worried it would hurt and I actually started with just 18 V (3 batteries). But as I realized there was little to no discomfort (for me) I upped it to a 4th battery and did 30 minutes per polarity. I did it 7 days in a row before adding glycopyrrolate to the water. By the 4th or 5th day I was sure it wasn't going to work for me as I had noticed no results even though I was upping the time per session each day. Then on the 7th day I added the glyco and I had already noticed a small cessation of the sweating. Marginal - but enough that I didn't think I was imagining it. After adding glyco (I put 3 capsules - 2 mg each in to each tray which holds about 1.1 litres of water - so approximately 0.05% as I read about in the study). After adding glyco I noticed some real undeniable improvements. It could just be coincidence and maybe the glyco doesn't help. As now I've heard many have similar "break-in" period for their ionto to be successful. Nonetheless I keep adding the glyco because if it ain't broke don't fix it. I did it for 11 days in a row total and felt pretty much dry at that point but didn't stop daily treatments until about 14 days. Then I decided to try skipping 1 day. Then after a couple on-off cycles, I decided to skip 2 days. Eventually after a month I was sorta forced to try to last 8+ days as I was on a trip. I did a 45 minute session per polarity just before I left. I went to Florida for 8 days and when I got back, I still hadn't had a single moment of even mild clamminess. Just completely dry. So now I do it once a week 40 minutes per polarity. I'm still on my original lantern batteries from mid december. I have 4 new spares sitting there waiting for when they do eventually expire. The added benefit as well has been about a 90% reduction in foot sweating. I've never done any ionto for my feet. Also the few times I have done it with a cut on my hand it did sting a little so when I say no discomfort, I just mean it's tolerable. I watch a movie while I do my session each week. This week I watched Expendables 2. Every action hero I grew up with was in it (except Steven Seagal - everyone hates him - lol). Pretty entertaining.
So anyways I hope this helps and if you have any questions - let me know.
I'm no expert remember. A lot of the people here like Sprawling, Amherst and 0707129r and many others are much much much more knowledgeable than I about all aspects of HH or Ionto. I had never even heard of it before December. Just one of the fortunate ones that it works really well for and because I know what it's like to live with it I stuck around on these forums hoping to maybe lend a hand.
Good luck,
Charles
