I have sleep issues, sleeping for about an hour upon going to bed, then waking up several times over next few hours. I have taken a sleep aid for quite some time, but sometimes just does not work. I currently take atorvastatin, 20 mg, lisinopril, 5mg, levothyroxine, 50mcg and 81 mg aspirin daily. Several of my friends take over the counter melatonin for sleep issues. Can I safely take with out interfering interactions?
