Hi!
People get treated for Lyme until every symptom is gone. It could go away with 3 months, or it could go away after 3 years of treatment. It's different for everyone. I think that you are probably better off being treated then living the rest of your life sick. Since Lyme is an infection, it will get worse untreated. You are also going to a LLMD, so I'm sure you are in good hands. They are very knowledgable. Yes, Lyme can cause insomnia. I get that, too. I'll let you know if I ever find some relief of that.
Good luck at your LLMD appointment!
