Hi I have been on clomipramine 20mg nearly a year now for obsessive thoughts which works but it hasn't done anything to help my anxiety or mood even at higher doses so I have had sertraline 25mg added and the first week I felt great but after 10 days now I just feel blah! Like a very low mood and just can't be bothered very tired, almost like a zombie feeling at times, will this pass? And is this a side effect? I just want to feel a little bit happier mood wise. Feeling fed up.
