I think something might be wrong with me. I woke up this morning feeling as though I was high out of my mind on something. It hasn't really gotten any better. Which, since I haven't had anything to alter my mind, is a bit scary. I honestly don't know if I should freak out about it or just go with it and enjoy the day.
Mucinex is a good product. Doc told me to use it recently when I had a sinus infection. The reason for your feeling "high" may be if you're taking a medication which is counteracting with some other medication you're taking. I won't ask what meds you're taking. Are you eating well and drinking enough water?
