Me two, but at that time they didn't know. IT has been a real struggle for me personally over the last ten years to promote HT as a treatment option for IBS. Many are like what is it? why would I do it for IBS or for a medical condition. Some think of stage hypnosis, which is totally inaccurate. Its also hard to research and even harder to get funding for it. Studies cost thousands to tens of thousands of dollars and its hard to do a double blind study with it. However its very safe and can be very effective for most people. I am not against medications, but if you can find something that can help without side effects that is a good thing. Also there are intergrative approaches, diet, meds, psychological treatments all combined.
You can't regrow and arm if you loss one, but you can regrow brain cells and regrow or change some nerve pathways for one.
