I began using the BW formulas in the past couple of months. I started with the EB-H6 formula without too much response. I worked up to the full dose fairly quickly, and went through a couple of bottles. Didn't notice much at any time on this one, so stopped.
Recently began the A-L complex, and was able to work up to full dose quickly. Some increase in fatigue and general sx, but not a major response.
Added the Envi-Rad, after my Assyra practitioner found it testied well using the Assyra. This one has been more potent! I had to start slowly (for me that was a couple of drops), but on about day 3 inadvertently took a whole dropper (got the bottle confused with some other herbs that I'm taking). I had a rough time with fatigue and emotional swings (not a good thing at work)! I did recover after a couple of days.
I usually can take a fair amount of anything, with the exception of DMSA and resveratrol, both of which I can only take like 1/20th of a full capsule. I would caution you to go slow, as I know someone who took 1/10th of a drop and became very reactive! As you know, terrible reaction means that the formula is working, so it's supposed to be a good indicator.
Good luck!
