Pradaxa- anyone else having issues with it?

I am 10 years post my ASD Sinuous Venousus repair. I notice I've had AFib more often in the last 18 months. My Cardiophysiologist put me on Pradaxa and within the first 6 weeks I went from active adult to full fledged slug. When removed from this med and put back on an aspirin routine I was almost back to myself within two days. Anyone else have problems with it:
