Flu

I was sick all last week and I still have a lingering annoying cough. I have the most trouble at night when I am trying to sleep. I have tried everything from alka seltzer p.m. to cough medicine, nothing works. So a friend of mine told me to try Theraflu. I bought some and drank it last night. She was right, I slept the most I have had in a week. I still coughed but at least I slept. I don't know if there is any better cure but I sure would be open to hearing any good tips. It makes it tough to feel better when you don't get any sleep and are so tired.
