Restless legs now after taking potent antibiotics

I posted here before about some of the CNS issues I am now having ever since taking a combination of antibiotics after a surgery this past fall. Again, I never had this issue either until taking this medication. It hasn't always been bad, but the past 4 weeks or so it really is hindering my ability to sleep much. Wondering if others have dealt with this, and how to remedy. I have Gabapentin to take, but it helps somewhat, but also leaves me really hung over the next morning (on top of the other fatigue/brain fog I have). Taking magnesium as well. I go to the Mayo clinic next week to get this whole adverse reaction I have had to the antibiotics, and this symptom is certain one that has been brought about because of it. But getting really desperate for sleep now.
