Hi! Okay, so I have a pet rabbit that I am very allergic to. Over the past three years (developed the allergy about a year and a half ago) there has been a lot of fur build up in the house. I know, bad me, but I've always been able to manage my symtums with medicine (Plus we will be moving at the end of the month to a much larger area that will allow me to keep said "beast" cleaner for me) but over the past two nights I have taken 6 Zyrtech D, yet I find myself wheezing and unable to sleep. Normally just one and some Vicks will take care of it. Please help. I need some sleep so that I can actually work on packing/cleaning after work rather than just feeling like a zombie.
