Aha! mine could be onions smell too, it is certainly that or garlic. I think your symptoms are similiar to mine and I may well be detoxing the same things as you. Do you get good days at all? I had a "good day" yesterday, cleaned kitchen, went for a 40 minute walk with the dogs, went to tesco's after lunch then rescued a hedgehog. As I expected though, within an hour of getting home my heart rate went up (and stayed up all night), head went fuzzy, and started to tingle - throat pumping. So I have had to just sit all day and drink salt water, this is how it goes: feel ok and do stuff only to get a relapse for 24 hours. Have you had the same thing? I have also wondered whether I actually have silent thyroiditis as that can follow a viral infection which was the start of all this 9 weeks ago- I definitely had hyper symptoms the first few weeks and it's sort of gone a bit hypo now apart from the increased pulse which would fit with the infectious nature of it.
