I've always hated the taste of Lemsip because of the paracetamol, don't understand how people can stand it.
I just take some tablets and have a mug of hot lemon/honey, the hot drink helps with congestion and the honey soothes a sore throat. Lemsip just mashes it all up into one powder.
I have never once missed it. I've already switched to Bluetooth for my headphones and car. At home I cast to the hifi or Bluetooth speaker.
I got an adaptor to let me use cabled headphones when I need to and I've used it twice, once was to test it even worked.
The use case just doesn't exist for me anymore.
