And is it horrific?!
I've got various allergies and asthma and while waiting for an appt with allergy specialists (because we still don't actually know what it is I'm allergic to) my asthma nurse has got me trying lots of different things. She got all excited when I said the nasal spray I'd been using had worked well and said 'ooh I've got something fun for you to try then' and gave me a sinus rinse and a load of sachets.
I stupidly watched a few YouTube videos of people doing it and someone said she felt like she was drowning! She did seem a bit dramatic in general though.
I'm desperate to get on top of this, and I really want to try it but I'll be the first to admit I'm a bit of a wimp!
