I had some old vicodin, 10/1050 hydrocodone/acetominophen, which expired quite a while ago. After lurking on forums like these I determined that it being expired would reduce its effect but not turn it toxic. Assuming it was weakened, I took 4 pills (40mg hydrocodone) this morning after doing cold water extraction twice, and sure enough the effect still wasn't very strong. About 10 hours ours later now, I'm worried that I didn't get enough of the acetominophen out. If I have too much apap in me, how long would it take for me to notice symptoms? Is 10 hours enough time?
