Doc put me on 20 mg Hysingla (ER Hydrocodone) a week ago for my back. It was working "ok". Pain was still there but subsided for a few hours towards the end of the day, since I take it in the morning. Last night it didn't help at all and barely slept because of the pain. Woke up and decided to take two. I've taken 50 mg of hydrocodone/acetaminophen IR over a 24 hour period before (usually 10 mg norcos every 4-5 hours) and tolerated it pretty well. Now I'm slightly nervous and hoping that I didn't overdo it since it's the first time with this medication at this dose, but I have been at the 20 mg/day dose for . Was just really frustrated this morning about the pain. I took it about 3 hours ago and I have about 9 hours until it peaks, so I guess I'll find out then.
