I'm using something different for my allergies this year. I was sick of the metal, dry taste in my mouth after taking Sudafed, so I decided to mix it up a bit! And you feel better about using these!
I'm using the kick butt allergy combo in an empty capsule but you can either layer the lavender, lemon and peppermint on the back of the neck, base of the skull.  Or you can mix all 3 oils in equal amounts to an empty bottle and add a roller cap and apply on the back of the neck, base of the skull. 
Lavender and lemon are also fantastic to add to the bridge of your nose for allergies!  Helps the drainage, and quick!
