Thanks, that is exactly what I've been doing, trying lower temps. I think I can handle 100 in the winter, but now in the spring (eastern Canada) I find that way too hot and draining. I actually have it down to 97 now. I think I enjoy it more for the jets, not so much the heat. Good advice re timing. I do have a habit of hopping in it right after work, and that zonks me for the early evening. I should wait until 9PM then hop in!
