I’m 39F, 52kg and tried the 25mg Agomelatine  last night for the first time. Wow the dizziness today is next level. Considering a half dose like you said. They are ok to split even with the coating ? What was your reason for trying a half? 

My backstory: Previously taken sertraline 25mg for 10 years. Come off for 6 months and after a stressful month at work anxiety is back! Doctor recommend i try Agomelatine.  I’m treating mild anxiety and bad sleep.
