UK mummies help!

Elsie
Hi, I'm just asking for help from UK mummies as I know in other countries there will be other products not available to me.. Anyway, I've got a
horrendous cold, know of any medicines I can take that won't affect breast feeding? I've had some hot soup and honey and lemon water but I feel rubbish. I plan to pop to tesco first thing tomorrow but is have to wait nearly 2 weeks for a Drs ap. I think I've just gotten so run down through sleep deprivation
