Sinus meds really throw me for a loop, so I try not to take them unless I just HAVE to. I get the Walgreens brand of Mucinex Sinus. You have to take it every 4 hours, but it keeps your head from pounding every time you move. I do have a prescription nasal spray I use when it is really bad, as well as taking a store brand Benadryl before I go to bed. That really helps bunches if you notice that they are worse in the morning.
