Yes I tried them and it caused me to get jittery. This was the first time on NB. Now I am working with a new practioner and he has me on 1 aday, he feels people who get jittery are not on enough magnesium. He has me on a low dose of supplements to see how I do because of the diagnose of Addison's disease.
I was pushed to get off my hydrocortisone when I first started NB and no way in hell would I do that. I need this for life support. Even though I got lower on my dose I can not live with out it yet and may never be able to do so. I did try to get off supper slow in 2011 and was off of the hydrocortisone for a week and I was so ill and could not even hold a tablespoon of water down me. So I needed to get back on the hydrocortisone right away. SInce then when I was working with this practitioner she realized I could not do with out it at the time. I listened to my body so I was able to get down to the 10 mg..
I know I could not do the coffee enemas of the sauna. Now My new practitioner informed me this will make you loose more minerals.
Just a warning, don't over do, you will need your energy to heal :)
