i can understand the agony you have. Change the medicine. start using Sudafed NAsal spray
Do you know your allergens, triggers and precipitating agents? try to avoid them.. use a surgical mask out side and indoor too if allergen is indoor.
Sublingual immunotherpies are used for symptoms not controlled by decongestants. but they are not allowed in US yet. Approved in europe.
Hope i was of some help. i will be here if you need any further, my profile has my contacts.
