Because it pales in comparison to the brainfuckery that I was having on the Keppra.
I'm at a beautiful balance right now - at 250mg of Lamictal, with the Keppra fading out of my system, I'm no longer having that hyperagitation thing, and I haven't had much of the brainfog yet. So my body is screwy - but my brain is fairly functional.
Of course, I have to dial back up to the brain fog and uncontrollable weight loss level of Lamictal. But right at this moment, I feel totally okay. Because my brain is mostly okay.
Did I mention that I bought a Flogging Molly shirt with a hippocampus on it?
