I have been on two kinds of anti-Ds. One lot about 7 years ago. They made me feel tired and very flat so when I got PND this year I was reluctant to try because I didn't want to feel that way again. I am on a low dose of a different drug and feel amazing! Feel like my old self and haven't felt this good for years! No side effects but tired at the start. I won't name them because different drugs affect ppl differently but I wanted you to know that there is hope that you will find the right one and function better. Good luck !
