I have started again on Parnate and have just gone from 10mg to 20mg daily after 3 days.
The problem is each dose only lasts 5 hours then it wears off , so I am only getting 10 hours a day of really good loss of social anxiety and depression. Then for the other 5 hours I don’t feel like doing anything and anxiety/ depression returns.
I used to be on 60mg. per day. Does anyone know why you can’t go up in dose faster ?
Especially when I was on 60mg. before and tolerated it fine ?
