I do.

No use in feeling sick if a safe OTC medication can help relieve my symptoms.
For a stuffy/runny nose I get myself Sudafed (pseudoephedrine). It's OTC but if you're in the US you need to show your ID and obtain it at the pharmacy (so Big Brother knows you're not going to make it into meth). If you don't need to show your ID you're buying the wrong Sudafed, which doesn't work for beans.
For pain I prefer ibuprofen, always on a full stomach.
And if I feel congestion in my lungs I take Mucinex (Guaifenesin).
And lots of liquid to say hydrated.
I understand your hesitation, but OTC medications are extremely safe when taken as directed on the package. They've been studied so extensively that doctors, drug companies, and the FDA feel that the use of such medications is safe without consulting a doctor.
You mentioned that you prefer "to stay away from anything unnatural." Can I ask what you mean? You also mentioned aspirin, which has the same active ingredient as plant extracts that have been used for thousands of years. Now, I'm not trying to convince you that aspirin is safe because it's natural. Rather, that being natural is irrelevant to safety and efficacy.
Think of it like this. It certainly doesn't matter if you take an aspirin or chew on willow bark; we can both agree that you receive the same ingredient and it has the same effect on your body. However, the aspirin is carefully manufactured to ensure that you receive a consistent and safe dose, and one that doesn't contain any contaminants. The willow bark, on the other hand, might (theoretically) give you the equivalent to 4 tablets of aspirin, not a safe dose. You just don't know how much you're getting. Likewise you could die from the ingestion of a parasite that was inside the bark. That's the problem with with "natural remedies" more often then not they do absolutely nothing, but when they do you don't always know what you're getting yourself into.
Here's another way to think of it. Like the example I just provided you, doctors took a natural pain reliever, took the time to study and understand it, isolate it, and then manufacture it in a safe and controlled manner. Scientists took something natural and made it safer. This has been done with thousands of treatments over the course of medical history: cures that are proven to work are incorporated into the field of medicine.
As technology advanced, humanity gained the ability to create new medicines, those that aren't necessarily found in nature. But this doesn't make them any more or less dangerous than those herbs and remedies found in the wild. Nature is a scary place: eat the wrong mushroom and you're dead. Personally, I'd rather ingest substances that have been studied and are well understood: so well understood that we have the ability to create them in a tablet form that I know contains exactly one dose and nothing else.
Sorry, did I go overboard?

In any case, feel better soon!
