Thanks for your time and replies. I went to a herb store and I was suggested to continue to take Goldenseal and raw garlic, ginger. I began taking Goldenseal early in the morning and since I wrote the mail I was able to get 3hrs sleep without coughing and the phlem has not been as yellowish and improving steadly. I am not throughup much phlegm too. It seems that I am ok for now. I am sleepy but otherwise feeling much better except for occational phlegm.
