I thought that is was due to the medications that he was taking so I called his PCP and ask him he said that he was not sure but the next time he is in the office he will look at it and see. 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.
