I have always thought that I just get sick easily. But I have a generally very healthy lifestyle, I am a surfer. But when I am at home, I feel stuffed up alot of times. It will switch from one side of the nose to the other. I sneeze frequently. When I go outside or am driving somewhere, these symptoms dissappear. So I am under the assumption now that I have major allergies to something in my place. I do have a cat, but I was never allergic to her for the first year or so. I have tried vaccuming the whole place, and I may feel a little bit better afterwards, but that could also be psychosomatic because it usually comes back the next day. My question is, what are the best OTC drugs that I can buy at the drug store for this? I have been taking Sudafed ever since I felt I had minor cold symtoms, but that only semi-helps me. I still blow my nose ALOT.
