I've had a pretty bad case of colds and coughs for about 2 months now, is this normal?

Although it has lessened a bit now, but still, I keep coughing up phlegm and my nose runs so much I can barely keep up with it! *That was a joke. I was figuratively speaking, people. I don't mean it literally.* I've been consuming a whole box of Kleenex a day! *Sorry, environmentalists. Didn't mean to finish up a rainforest.* Anyway, I was taking medicines for the first month, but now I've stopped. I took : Zinat *I'm not sure if this is how you spell it.*, Neozep and Ambroxol. I've stopped because these are too expensive and they don't seem to be working much. I have a healthy diet. I have fruits for breakfast and I eat vegetables for lunch and dinner, but, this cold and cough won't go away! I was wondering if this is normal, and if there's something I can do about it. It's summer here in the Philippines, but I'm not sure if this still qualifies as a summer cold... Is it a virus? Is it a flu? I don't have a fever or anything else. Just these darned colds and cough! *sniffle,blow nose*
