Re: Does this sound like an increased dose?
You're getting the same amount but it is spread out. I got much better results with the short acting percs too. They enter your system much quicker but they also leave much quicker. If you were taking 10mg of percocet at a time and it hit your system in 30min, and then went to 10mg of percocet that delivered over a time span of 8 hours or something, it is only common sense that says it will work differnetly and probably not as well.
It might help to figure out when to take the 5mg of short acting with the 10mg of long acting for the best results. Talk to your doctor though, this is just my opinion.
