I started flagyl at six or seven weeks, so I'm all for starting at two months. Remember, I started abx immediately after being diagnosed, so your mileage may vary.
Start gingerly and work your way up slowly. No need to do what I did and begin with a full five-day pulse. You'll have time enough to work up to full dosages.
As for the spasticity, you have to remember that abx therapy doesn't stop the MS/cpn infection in its tracks. First, the abx have to get in there, then they attack the bacteria while its still conducting its business of multiplying and entrenching itself, then the abx kills more and more of the bacteria until you get to the point where you're no longer generating more bacteria than you're killing. Depending on your bacterial load, this could take a while.
Add in the fact that you will now experience die-off and the resulting toxins will be floating free inside you, making you feel like dog food. And die-off causes inflammation, which means areas of infection will be inflamed (just like in a real MS attack) and those 'pseudo-exacerbations' will scare the heck out of you. THey're no longer the result of your body chewing on itself, but they will FEEL real. This bacteria will not go quietly; it's going to try to convince you in any possible way that killing it is not a good thing. Remember, if you quit abx, the bacteria gets just what it wants - a docile host for it to use, abuse and eventually kill.
