I wanted some heavy duty cough syrup as have spent the past 3 days not sleeping at all and not keeping any food down due to the violent coughing. She advised me to use lemon and honey as most cough syrups contain a small amount of alcohol and 'you can't drink alcohol whilst you're breastfeeding a baby' 
My response, between hacking coughs, was 'of course you can, although I prefer to wait until he's gone to sleep'
then one of the women who worked in the shop said 'ooh, no you can't, that's why I didn't breast feed, needed my wine too much!' ha ha ha.
I went to a different pharmacy in the end. but wtf? I've half a mind to print off some bfn fact sheets for them. I know it's not recommended to get leathered and bf, but ffs, how much cough syrup did they think I was going to get through?!
