Help! I have been on flagyl for 3 months titrating the dose up to 1000mg twice a day. I began stuttering and twitching about 2 months prior to the flagyl.Its not getting better except for a day or 2 a week. I am also taking biaxin 500mg twice a day. I am thinking of changing to zithromax soon to save some money. Have any of you had these symptoms? I have been treated for nearly 10 years, and most of my symptoms are neuro, but now i am getting nervous. I also take slo mag twice a day. Any comments or suggestions or any kind would be so appreciated.
