I take generic Lamictal for treatment-resistant depression. Probably related to the Lyme and Cpn infections.
It is used for seizures, some for bipolar, and depression. It's really helped me cause SSRI's quit working.
It helps to work up slowly on the dose. Headache was a problem and I didn't feel well, but I did adjust to it.
What dose are you on? You may not need as much as they use to control seizures.
Also a sleep study might be useful to help to figure out if your motions are giving you a low quality sleep.
Ugh. Wish I could sleep more than 5 hrs a night.
