I am taking hydrocodone/apap 5/325, 2 tabs 3xday for arthritis and degenerative disk dx in the spine. Plus I fx'd my spine in T- 11, 12, L-3, 4, 5 in 2009. I also have a case of arthritis at the CMC joint of the thumb. Very painful in its own right. The dose of the six tabs a day seems to be ok to get me through the day but I wake up every night and can't take any more of the drug without exceeding my 3xday dose. Can I take an extra dose to get through the night therefore making it 4xday?
