You say a foot bath will help could you kindly explain? Are you saying to soak your feet in one of those foot baths that massage and vibrate your feet?
I've been trying to develop MRT too, but have not had much sucess. I've read that along with making sure you are hydrated, you should keep your tongue off the roof of your month, and I think it said to keep your mouth closed and also that if wearing jewelry or a watch it could interfere.
