Wondering if anyone else is on this newest med of mine and if they can answer a question.

Today was my first dose and it sent me into zombie mode for a couple of hours, then I fell asleep watching a movie (not a big deal since I was home alone) but I woke up with a headache. The headache seems to be getting worse, and I know this is one of the common side effects, though I cannot for the life of me explain why a pain pill causes new pains.

Was wondering if anyone else is on this and if it took very long for your body to adjust to it.

Still trying to figure out if it is sae to take advil with it.
