Well there are those that get to 80-90% of their former selves faster than others. Most of this is due to the Lyme Dr. addressing the other issues outside of lyme like, babesia, bartonella, ehrlichia, mycoplasma, viruses, yeast, vitamin deficiences, toxins(mercury etc) exercise etc.
Basically if you spend most of your time chasing lyme with single drug regimens, you should expect this process to take a long time and miss several key aspects.
Most on here appear to make it to the 80-90% range within the first year. The second year or two is when most of the final resolution of symptoms occur.
The sooner you find treatment following the initial onset, the sooner you will get better.
