See an allergist.
Allergy shots (immunotherapy) is homoeoepathic therapy (well, technically homoeotoxic), completely "natural" and works better than any drugs out there, because it trains your immune system not to go crazy when it sees the allergens.
There are other non-drowsy drugs out there - people have already mentioned Singulair and Allegra. Singulair is particularly effective if you do have asthma, but it really doesn't sound like it to me, either. Did your doctor give you a breathing test?
I do take the drugs when I need to, and sometimes irrigate, but nothing's improved the quality of my life more than allergy shots.
