i am on pregabalin and have been for three years for my anxiety however it has made my self harm worse and the weight gain is unbearable. i was on 400mg but have weaned myself to 300mg and am starting to feel better. i want to wean myself to the next step of 200mg but everytime i try i start to struggle and the anxiety gets worse. how can i manage this to be able to wean myself to 200mg in order to stop taking pregabalin altogether?
