No, what you need to do thistle is burst into dramatic tears until he buys you the biggest chocolate cake in the store and a big bunch of flowers to make up for it. 
Lemsip is, as far as I'm aware, off limits. 
I've been surviving on paracetamol and Vicks, which barely take the edge off. Saline nasal spray is considered safe, and I think some of the allergy sprays are ok as well - but check with a pharmacist.
Otrivine and the like are not tested for pregnancy, which doesn't necessarily make them unsafe. General consensus is that they're probably fine, as so little of the chemicals get into your system. But it is kind of a "Use at your own risk" choice.
Personally I'll be avoiding using a nasal spray for the first trimester but then might use one overnight for the later trimesters, especially if it's like last time and I get a cold every other week!! I might use the child one though, so the dose is weaker than usual.
I work in the centre of Leeds, Lolly. :) If it's convenient, maybe we could meet up for a drink next time you're in the area for a meeting? Very jealous of your takeaway! I was meant to be making a curry tonight, but I'm shattered so we just had pasta. Again.
Are you allowed to take your DD along to the 12 week scan, Halfbaked? Here there are no children allowed at the NHS scans. It's one of the reasons we're contemplating a private reassurance scan at 9 weeks then a gender scan at 24 weeks, so we can take DD along and manage her expectations.
