I think it would depend in part on how much you are willing and able to do to accommodate your special needs. Many years before my diagnosis, I took a scuba class while living in Germany, where the lake water was quite cold even though it was June. I was also still breast feeding. I ended up dropping out. It was just all too much and I didn't have a diagnosis yet so I didn't really know that I needed special consideration, much less what kind I might need.
So, if it can be done successfully, I would assume you will need to do some "extra" stuff to make it work.
