thats ok.
regardards to the heat, when the temperature first started to go up I find my symptoms subtly changing, breathing, pain, etc I can tolerate 20c. however yesterday being much warmer my body is starting to complain more, like you say tiredness, overwhelming tiredness, dizziness is much worse to, my joints are protesting also!
hope you feel a bit better soon. (obviously a lot better, yet I know how eds works!)
