Drugs themselves are unlikely to make this better.
It is important to treat risk factors such as blood pressure and drugs can be helpful for this.
Also very important to deal with lifestyle issues such as being overweight / obese. There is fantastic data from Australia showing that reduction in weight significantly improves atrial fibrillation symptoms, and also has effects on diabetes and blood pressure. Not a great deal of data to support other lifestyle measures, but caffeine doesn't seem to make a difference. Intuitively exercise, eating healthily and not being stressed would help.
Of course, we do have lots of medications and procedures that can help and I'm sure your cardiologist would be very happy to discuss this with you
