Hi, I have a cold with fever, cough, and nasal congestion. I already took 4 pills of Mucinex during the day with a 4-5 hour interval. Than after about 4-5 hours after Mucinex, I took 1 pill of excedrine. It was around 4.5 hours ago. Now I cant fall asleep and want to take 2 pills of Mucinex Fast Max Cold, Flu & Sore Throat. Can I do that?
