Well that was an exercise in futility. Got to the medical practice and not only did they not have me down for an appointment (even though I'd booked one earlier), but they were just about the most unhelpful women ever, saying it would take 2 weeks to register, and then another week to get an appointment! And they just stared at me like three gormless garden gnomes, without any empathy or helpful suggestions. WTFFFF??? I've left them a stinky review on the NHS pages, to join others that were already there.
London is so much better equipped for emergencies, with loads of walk in clinics everywhere. Here I'd have to drive 5 miles, not a lot I know, but I'm so exhausted, I'm not sure I could drive safely.
So then I thought I'd just buy some codeine and maybe that would knock me out. No sorreee - turns out you can't buy it over the counter any more, you need a prescription - and for that you need a doctor. So we come full circle. I sat in the car outside the pharmacy and had a cry, then pulled my big girl pants on, came home, searched the cupboards, found some Paramol (which has codeine in it) and a few sleeping tablets, so will give them a whirl - safely, I promise!
