Oh my goodness, you poor thing! Taking all that stuff....you must rattle when you walk!
Ok, British home-made remedies! For a cough - a big spoon of honey dissolved in a little hot water, sipped as a drink.
For a dry tickly throat - a big glug of ordinary malt vinegar, a teaspoon of sugar and a little hot water, sipped slowly. I can remember my dad making this for me as a child in the middle of the night...it tasted a bit disgusting, but my goodness it worked!
Good luck, hope you feel a lot better soon! Sally x
