You made the step to get over-the-counter drugs instead of the prescription ones. That is really great.

I hope you dont become a cough syrup junkie though.
I think an even better step is to go herbal remedies (very safe).
I have found that Echinacea (the best thing I have found for the immune system and the most popular health herb) has improved my health and "not" covered up symptoms. There are many great herbs that help your body get well. I think the key term here is "help your body".
Herbs are not a quick "fix" though. It takes time for your body to heal.
Get well soon,
