Well, I know that there are different effects for different people. But I was taking "non-drowsy" nasal decongesting Sudafed and man, this makes me feel good. It's not like it's addicting, because I only take it when I need to but this makes me feel like I'm floating. Also, its makes me yawn a lot. Here's a tip- NEVER, and I mean never, mix Pseudoephedrine Hydrochloride with Ibuprofen.
