I tried 10mg IR and 20mg IR, with great success and only mild
side effects but they did not
last very
long maybe 5 hours max, and I have 13-16 hour work days. So he prescribed me 25mg XR, which worked beautifully for the first month, aside from only lasting 8-9 hours and making me feel cold (which I’ve always had cold hands and feet for as long as I can remember).
