I have been prescribed hydrocodone 7.5mg (pain killer) i have never been prescribed a pain killer before. I injured by back at work, and the hydro's help however i am thinking about not taking them anymore because of the side affects. i have about 36 of them left and i know that they can become habit forming but that is not my issue. they make me very drowsy almost light headed, my memory has also been affected. i had to look up my mothers phone number. i have been dialing that same number for 8 years and i had to look it up today because i could not remember what it was. if i am trying to enplane things i have to take my time because i cant recall information correctly, the pills are also affecting my dreams i tried to take a cat nap earlier and i had a dream that my roommate handed me the phone but i could not move. i could not talk i was frozen/paralyzed i couldn't even open my eyes. i don't know if i should try to bare the pain or just keep on with these concerning side affects. i am not sure that the side affects can become worse or case further damage. any information will be greatly appreciated.
