I used pharma abx for 12 months in 2007 and only got worse -completely bed ridden and seizures.
In 2010, I used the Chronic Tonic for 12 months (Houttuynia for the last 9 months) and was healed for 2 years before I got reinfected.
They affect us according to our weakest points in our bodies, even if we didn't realize that it was a weak point, and go from there. Mine is my intestines, and boy do they get hit hard! But that's not my only weak point, so there's lots for them to dig in deep with - so to speak.
It's the toxins that make us the most sick and what drives our symptoms, so if you can detox enough, then you won't feel as bad. Each time I get lazy and slack off on my detoxing, I will feel worse and have symptoms increase. It may take several days or even up to just over a week, but it always happens.
While they can most certainly cause damage, most if not all, is only temporary and the body can heal from it. Yes, even the nerves can repair themselves!
I did a lot of hand quilting when I was really ill the first time around, and because I had such terrible nerve problems, I couldn't really feel my fingers and would frequently sew them to the back of my work - a little embarrassing, because it never hurt, but could get a little bloody sometimes! LOL! I would also burn myself, and could use really, really hot water!!! Which wasn't the smartest thing, but I couldn't tell when it was "too hot" until it was also too late.
It took a while (maybe 9 months?) but once my nerves reached a certain level of healing, I suddenly got the feeling back!! What a shock I was in for when that needle point really hurt!! LOL! Or my hot water was actually very hot to the touch for me!! LOL! I still find myself "admiring" the way things feel, a super soft blanket, the feel of water running over my fingers, the feel of my dog's fur, and so on. It's amazing since I didn't think I'd get it back. I made sure to continue to take many supplements and herbs that aid in the healing of nerves - and now I'm back on them!!
Ultimately, no one knows what will return or to what level it will return for those that have long standing chronic infections, but it's all worth fighting for!
And congrats on your brain working again!!!
