Can you get into the military with epilepsy?

I have always wanted to go to the military since I was a young boy. All of my family has been in the armed forces at one point or another. I have always been pushed to go to military schools and academies. Now that it is about time, I have epilepsy and have been seizure free for 3 years. I know that there are appeals that you can get. But for epilepsy how common is it to get a waiver? It has been a dream to serve.
