I was fired from a job last year for poor performance, I later figured out that it was due to being over medicated due to severe migraines. Here is a little back round to give you a better idea. The 1st job I had out of college I held for 10 years, I was let go due to corporate downsizing, company is in big financial problems and I was 1 of 120 people let go at the same time. About 8 weeks later I found a new job job at another big company, but I struggled with learning the new position and retaining the information. I was fired from this job after 6 weeks. I later figured out that one of the medications I was on to treat my migraines was severely impacting my ability to think clearly and to focus, the medication has since been changed and things are now much better. But how do I explain this to potential employers without scaring them away?
