Please don't stop abx on your own. Talk to your doc. Rest whenever you can. Try to get your 'sleep hygiene' as good as you can.
Here is a little tidbit I copied from here;

For Lyme patients, ‘sleep hygiene’ plays a vital role in the maintenance of everyday health and well-being. Supporting the internal clock with healthy sleep habits and a sleep-inducing environment helps.
* Tuck-in at the same time every night and wake-up at the same time every morning. Maintaining a regular sleep routine goes a long way to signaling when it’s time to nod off.
* Skip the coffee, tea, chocolate and any other stimulants that challenge drifting-off. If coffee is a must in the morning, opt for decaf or switch to herbal tea.
* Draw the blinds. Make your bedroom as dark as you possibly can for sleeping. The sleep-inducing hormone, melatonin, increases in darkness. Boosting melatonin levels equals more shut-eye.
* Shhhh! Keep it quiet. Take the TV to the den and keep the computer out of your bedroom. Clear your room of electronic gadgets to minimize sleep disruption.
* Practice calming, stress-relieving behaviors before bed. Lyme sufferers often struggle with related anxiety and depression. Calming behaviors like prayer, meditation, and gentle stretching (not cardio) can relax the body before lights out.

Another thing that helped me was using lavender oil. Every night I would put a few drops of lavender oil on a piece of fabric, put that piece of fabric into a sandwich baggie - leaving it
open, I would then slide the baggie under my pillow at night. I also take melatonin & magnesium oxide at night , just before bed.
A good herbal tea is Celestial Seasonings "Sleepytime tea". (I in no way receive any type of compensation from this company).
Hope this helps a little.
