But my question is he takes plavix, aspirin, lisinopril, Zocor, Zoloft, Coreg, lithium, and
methadone. I took him off the lithium thinking that was the cause because after doing research sleeping all the time was something major with that drug. I was also thinking that it could be the Coreg because they up the dose last time he saw the doctor but that has had time to get in his system and not be the problem.
