I think it says "waking hours" because, if you got the same prescription I did, it says to take every 4 hours, 5 times per day. Well, that's 20 hours and most of us aren't awake that long. So I think it just means that you don't have to set an alarm and wake up to take one if you're sleeping.
I took mine on this schedule: first at 7:00 a.m, then 11:00, then 3:00, then 7:00 p.m., and last at 11:00 p.m.
But on the weekends when I wasn't up and 7:00 a.m., I took the first one later, but then didn't get that fifth one in before going to bed.
I ended up getting a second prescription of the same meds because the day after I finished the first prescription, it started getting worse. So I called the doc and got the second prescription so I was on the meds for two full weeks.
After the outbreak started, I realized that the morning I felt like throwing up and the mild diarrehea (SP?) I had were probably symptoms but I didn't pay much attention because they weren't that bad.
I am sooooo sorry you have this. I am just now getting over mine, 3 weeks later. I still have what I call mild pain, but Advil seems to relieve that.
If you're not taking any pain meds, I would recommend Advil. It really helped me.
