My Parkinson's symptoms how did they progress?

The first symptom I noticed was in the summer of 2012. I had some symptoms before that even. The first symptom I noticed was not tremor. Can you guess what it was? Let me know in the comments if you guessed my first symptom and the first on I noticed.
