I'm surprised no one has replied to your message. Often when people are starting an antibiotic protocol, they experience a worsening of symptoms such as yours. I think it is usually recommended to keep backing off until symptoms disappear, then building slowly back up to 200mg/day, as it becomes possible. I hope you're already feeling better and this note is meaningless.
