Well, I don't need to explain why I cannot stand TEA tea, I've been a life long teapot, as is Liz, kettle never cools down, but I will.
About 13 years ago I was making us a brew, and I got a whiff of the smell of the tea, and although I still make it for Liz, I cannot abide the smell or the taste, I did try Earl Grey for a while, and other types, but none passed my lips for long, I still like a hot drink, and I like coffeee, but I don't always want coffee, so I tried Mint tea and have got on with it fine until we moved here, the water must be different as it just taste bitter to me now, and I could barely dip the bag in the hot water, it became pointless, buying it so when I went shopping last week I bought Lemon & Ginger, I can leave the bag in and no bitterness.
Along with the not liking the smell of real tea came another problem, I had the smell of tea in my nose for weeks, then it would vanish, and weeks later another smell would take its place, usually again for a while. This was mega annoying for me, I could still smell everything else as normal, but I Googled it and it's not uncommon, and can be a sign of a possible stroke, so off to the docs, and I was diagnosed with both Phantosmia & Hyperosmia, no joke I can tell you as it pervades your whole life, it is only slightly better when out in the fresh air or where there are really strong smells, but you can pick those up and be with you for ages too.
Anyway, I eventually got to ENT (19 months waiting) they shone a light up my nose, then sent me for a head MRI, being claustrophobic didn't help, they put this cage around your head, then some weird upside down mirror glasses thing, and you have to lay completely still.
A few months ago they called me back in and said that there was nothing they could do as they couldn't see what the problem was, so I'm stuck with it forever it seems.
