It seems much longer than the 20 days that have elapsed since my adventure in Wyoming. After returning only 3 weeks ago tomorrow, we (Richard and I) began flagyl 2 days later on Thursday night. My own response was the usual short hour until loss of function - a little less than usual - and mental confusion - much more than usual and the lethargy lasting for days. I still have the emotional flatness and great amounts of slow, fuzzy thinking. And the vertigo, something always present, this time in huge waves requiring me to hold on and wait till it passed every time I changed position. Even now, 13 days after ending the pulse, if I move suddenly, I must stop and wait, but briefly now. I look at this pulse in wonder. My walking deteriorated but less than in the past and for the first time I had a slight shortness of breath, now gone. It was very different from all the ones proceding it. My hope is that I am reaching a dividing line between the physical repair and beginning a much deeper burrowing into the brain. I have tried several times to extend my pulses with limited success and am almost looking forward (crazy!) to the next flagyl to see what the rewards will be.
