I have more faith in UT than I do megadosing Vitamin C, orally or in IV. I'm going to back off Vit C and do UT now, as I seem to tolerate UT better than I used to. I took 1/2 Cup on arising today and another 2 oz later in the day. I might take two oz 4 to 5 times a day for a while, and even stay at that amount. I cut back on meat too, so I don't get too acidic. :)
