Recently got prescribed 25th a of lamictal daily, going to up it to 50 in 9 more days. 

Since taking it, I have had the worst runny nose and sinus pressure and sore throat. Generally just having a hard time and nothing is helping. I can’t really take Benadryl because I have three kids and can’t sleep all day. 

Is this common or is this just something I’m being silly about?
