Pain diary advice

Hi all! My new Pain Management Doctor prescribed 5/325 Hydrocodone #40 and a pain diary. It was explained to me as I should take a pill every time the pain is at an 8+/10 and to document the activity, time, location, etc. I’m still a bit confused on how to properly complete the pain diary.. My pains an 8+/10 the second I wake up in the morning so I would take a pill and record the activity, an hour later, it’s still 8/10 so I would take another. Obviously I can’t take them every hour and throughout the day my cervical and shoulder pain worsens. I feel as if the Hydrocodone doesn’t help much, if at all and I believe the Acetaminophen is making my belly hurt. How should I record this in my pain diary? Continue to document the pain but only take a Hydrocodone every 3/4 hours? Thank you for your help!
