Wow. Patrick, that is a great post! So cool that the hospital can and will incorporate SFQ into its health care procedures!
As for your question, it is a very good one. I don't think anyone can give you a definitive answer. To some extent, you have to answer it for yourself. If you are getting benefit and results from the Swimming Dragon qigong and from the Zazen practice, you might want to continue them.
But I understand that time is a factor! When do we do all these things? The rule of thumb for SFQ (and many other qigong practices as well) is it is best to allow at least a half hour "window" or cushion between practices ( it is still good to at least allow 10 minutes, and even better to allow 20 minutes. 30 minutes or more between practices is best). Again, this then impacts on our schedule in terms of time. But if you get benefit out of the other practices
AND SFQ, then it might be good to try and schedule your day, or at least your week, so you rotate all of your spiritual/health practice.
I used to practice ZaZen sitting and I must admit it was a wonderful and powerful practice. That might be the first time I really understood about "the Emptiness".
You really have to answer this for yourself, keeping in mind the rule of thumb and your schedule. As well as the cost/benefit ratio (in terms of time and effort) of all the various practices.
You might also want to consult your Master's energy by meditating and asking the question. And most likely, you will know or get the answer that you need.
I hope that helps you. I thank you for asking, because it helps me to write this in response!
