I went most of today without a pain relever and i felt bad, not just my back but tired and kinda dizzy, so i took some bayer asprin instead and i felt better afterwards...could i be addicted to pain relevers? i cant go without it now at work. its not just my back that hurts, my head and im dizzy sometimes

also i wont get into my doctor til the 27th, so til then is taking bayer safe for 2 1/2 weeks?
