Yes, in Truth, no medication is ever needed and there is no need to be limited by anything material. However, the way I think of it,
- the body is what the brain tells it to be;
- the brain has been programmed by our childhood and adult experiences and decisions;
- that programming has trained the brain to block input from the mind;
- as we learn to let the mind have more and more access to the brain, the brain gives the body new messages;
- the mind, our spirit, soul-Self, is infinite and unbounded;
- so the new messages move the body toward unlimited health, unbounded strength, and immunity to whatever is happening in the material world
Now, as you're doing the clearing work, however, as you release and replace more and more of the brain’s programming, you will find that fewer and fewer of those old programs apply and more and more of your spirit-Self is your experience.
So, as you go along, if you're paying attention to what you're thinking, and that thinking is focused on the spiritual reality of you, rather than the past experiences of the physical-emotional body, AND you can trust yourself to deal with any issues that may come up, you can feel free to do whatever feels right in the moment.
Be aware, though, that the brain's programming runs deep, so you may find there are ups and downs along the way, as you make the shift from one state of being/consciousness to another.
