So it started a couple of weeks ago. I bought a cheap reed diffuser and it smelt like that horrible cheap perfume they put in sanitary towels. I binned it and bought a new one from Next - Lemongrass and Yuzu - I love citrus. It also smells of perfumed sanitary towels. Sunday I went for a long drive and I could smell sweet burning - I thought something in the car was going to go bang but it didn't. Got home and could still smell it, so not the car. Tonight I was straightening my hair and there was something pongy - I thought it was me after a hot day! So, I just ran a bath. Usual shower gel which I love - smelt muddy. I unplugged the bath and got a huge whiff of rotten eggs! What's going on? I don't have a great sense of smell usually - I washed all my sofa covers yesterday and can't smell anything from them, they should be lovely and fresh. I'm a bit weirded out tbh.
