I have been on Brintellix for 3to4 months starting at 5mg gradually increasing to 20mg/nocte. It has helped with the depression but I have no energy or motivation. Specialist has just prescribed Valdoxan to help with anxiety but I feel so flat and am crying a lot. I am also noticing muscle fatigue and force myself to walk the dog just so I am doing something, are these tablets any good? I have been prescribed every anti-depressant known to man this is first that I think is helping but the side effects are lousy.
