I found out my sister's on it as well.
The doctor said it could take over 2 weeks for the duloxitine to be out the system worst case 2 months....
Main problem is I'd like to go out without having to worry about my t-shirt getting soaked from sweating mainly my back area,which only started right back when I was on serotonin.
Doctor told me to take it in the morning as it tends to give people an energy boost and I'd struggle to sleep on it,although my sister takes it twice a day morning and night??
