I have been taking Sertraline for about 10 months at night . Wonder if I should switch to taking it in the morning as I am told it may be interfering with my sleep ? Started with 50mg for about 6 months then it was increased to 75 for 4 months . I fell into depression in April of 2015 . I have great difficulty falling asleep at night . Also taking .25 mg of Rivitrol about 3 times a day . Have been getting a lot of headaches . The rivitrol acts very quickly but my pharmacist would like me to stop it but when the pressure builds up the only quick relief is Rivitrol Also my hearing has been badly affected & am waiting for a hearing test . I will be turning 86 on Aug 2/16 --G-d willing . It s been a long time enduring my depression but I am very active by attending Mondays & Wednesdays at the gym- Tuesday at Group Drama Therapy & Thursday at a recently formed singing group. I recently passed my medical for driving.
