CHfather, I will try it out on the weekend so if I stay up it won't be a big deal. If it works for me I'll be glad to stay up a little late anyway
I am in the US and you hit the nail on the head when it comes to O2. In my area some companies restricts sale to vets only.
spiny, thank you so much for all of the ideas!! I have noticed going outside in the winter makes me feel better. I have yet to try cold head/warm body in the bath, but look forward to seeing how it works. D3 seems to be a recurring aid and I'll work with my GP for blood work.
LIke CHfather said above, it shouldn't cause many issues and I can always stop if needed.
