Can we beat Mysthenia Gravis?

I just want to confirm with u or other that is is true that we can beat MG or MG is cureable? Bec. for me it is impossible. I m suffering from MG since 2000 when I was 21 years old. Like u I gone through thymatemy but it didn't work. I was taking predinisone 250 mg daily when I saw a new doctor bec. I was started to feel weekness. and he said that I have no MG he stopped my medications. After this I suffered alot from MG crises that even I couldn't walk or stand up. Than I go to my old doctor and he started mestinone again with prednisone and Imuran and slowly I back to life. Since than with more or less medicine I m trying to control my condition and thank God I m good. I have two kids now. Right now I m taking mestinone, 10 mg prednisone and Imuran. Doing regular exercise and living a happy life with kids and MG. Kindly plz guide me is it true that MG is cureable or not. Bec. of my past experience I m so much secard.
