I'm dealing with allergies pretty badly because of dust and strong perfume smells. It gets to the point where I'll sneeze non-stop for like 10 to 15 minutes, often more than 15 times. I've been using MONTEMAC FX or MONTEMAC L to help with it and while they do work, the side effects leave me feeling super sleepy and just not myself the next day. I've also found out that I can't take levocetirizine and anything with FX. Can you recommend something else that won't make me feel drowsy?
