I have allergies to everything so even though my allergist would like to see me off of drugs from Nov - Feb I can't. I did just try again and only made it two days. I get dizzy, lightheaded, and nausous. I do not get the typical allergy symtoms at all. He said I just swell up in my head. So I basically take Zyrtec D and Singulair and Rhinoquart all year long. Does anyone else do this? Will there be any problems for me doing this down the road? I also get allergy shots, which I'm wondering if I should just stop. It's been almost two years.
