I used to suffer from severe allergies, asthma, and chronic fatigue, even though I had been taking 500mg/day for years. When I read Cathcart's protocol, I increased my doses to 5g the 1st day, 10g the 2nd day and then felt well at 20g the 3rd day. I tried to increase a bit more but right away the soft stools came. I took that for 7 years and it kept my allergies under control and the differences in my energy were night and day. I tried hitting the gym pre vitamin C a few times and always felt like I was going to die. When I am on the bowel tolerance doses, I have so much energy I have to workout regularly or I can't sleep. I hardly take any days off. I'll be 48 in a few months and am in the best shape of my life. Interestingly, when I was injured in an accident in 2010 and could hardly move around, I put on 30 lbs over a year. Then I started working on classifying and organizing the content of my transcripts of 54 hours of interviews, and read Dr. Hoffer's advice on people with allergies. In the heat of the moment when filming I hadn't caught it... He advised a 2 week exclusion diet for lactose. I tried it and by the 3rd day had to cut my vitamin C dose from 20g a day to 10g a day (5-10g is normal). Plus I started breathing through my nose for the first time in my life! Doctors had taken x-rays of my skull and didn't know what was going on. Turned out to be a result of my body struggling against a food intolerance. Without any activity and eating and drinking the same (besides the lactose free) I lost the 30lbs over 6 months. Now I recommend people who need huge maintenance doses of vitamin C investigate whether or not they may have food or other allergies causing the need for such a high dose. Since starting 10K IU daily of D3 and also taking a bunch of other things, I'm down to 5g a day now.
Thanks for sharing.
