I will start off by saying that I love this stuff. I tend to start getting stuffy during the spring months because of all the pollen. This stuff is a lifesaver for me. It says that it gives 12 hour relief and I really believe it does. I get really bad sinus headaches and this provides the ultimate relief.
I will say that it says you can take it all day, but it usually makes me tired. I am not too certain if I can blame it on the medication or being sick though.
I think that the caplets are the perfect size and easy to swallow. I noticed that it also takes away all my aches and pains everywhere else too. Bottom line is that this is well worth giving a try. It's inexpensive and can be founds anywhere they have a pharmacy.
