I would have to respond that there aren't really any typical symptoms! Lyme can mimic the symptoms of more than 300 (yes, 300) other diseases, and it seems that everyone has their own unique mix of responses to the spirochete. The dastardly thing about Bb is that it changes forms, so depending on what abx you took, you could have killed most of it and the remainder could have gone deep into hiding and gone dormant into its cyst form, and then not been evident again until recently. Some people have the infection for years without ever having it develop into disease.
The foot pain especially first thing after waking, the muscle spasms, and the tingling are all commonly occurring Lyme symptoms. And yes, I know (and have) the balance problem. It's a strange feeling, isn't it? Sometimes I'll be walking along and just lose my balance and have to step sideways or put my hand on the wall. I don't have the fainting sensation, but the falling over, yup! I've never had any sleep issues either. My most severe and debilitating symptom is the joint pain. And I guess the fatigue. Don't have too much memory loss -that I remember anyway -but I do have brain fog, which is thankfully getting better.
Last time I was in my LLMD's office there was a new patient there and she was talking about being only 50 years old and unable to put her pants on without sitting down. I had to tell her I wasn't laughing at her, I was laughing with her, because, although I'd read about it, I hadn't met anyone before her (and now you) who had falling over as a symptom! I was a ballerina for 17 years when I was young so my balance has always been excellent, and now I can't walk around the bed without putting a hand on it for balance...
I would say keep at it, and remember even the CDC says diagnosis of Lyme is a clinical one, not necessarily one of test results. Best of luck to you, I hope you feel better soon.
