Hi, Ive recently had a cold that ive now sort of recovered from. The only problem is that its left me with an irritating cough. Its usually worse at bedtime. I find that im drifitng off to sleep and the cough gets so bad that the tickle in the back of my throat has to be relieved with drinking water constantly which wakes me up a few times during the night. Ive never had asthma and I do smoke. I was just wondering if there is anyway to treat the annoying cough I have?
