pain
"Severe lower back pain. Took my first dose last night. The caffiene in it, kept me awake all night. Took another dose this morning. The caffiene makes my heart feel like it's beating out of my chest..the codiene in this medicine did help my back pain..I eat before I take it, because it does upset my stomach.. I will be talking to my doctor about switching to something else. I'd just rather have plain old hydrocodone ....no caffiene ....."
