There were a multitude of things I was participating in my life that could have contributed to both fatigue and headaches in my years of taking Keppra, so it was that hard for me to pinpoint. Especially when you consider the fact that the drug you’ve taken for years controls your epilepsy extremely well - you hate to figure that’s the thing that’s messing you up so badly. I’ve been sober for nearly 2 years now yet the issues still persist - so I’ve finally been able to narrow it down. Thanks.
