When I first started taking it it did make me sleepy. But now I'm used to it.. I got over it after about the first week. I don't take it unless I'm having a lot of pain... I know, I know.. but I don't take meds as often as I should sometimes. Doc told me I could take Ibuprofen with it. You might want to double check with your doc about mixing any of the meds though.
Sorry I couldn't be more helpful.
Good luck tonight..
