I am newly diagnosed too! Before I started taking adderall I always felt anxious after drinking coffee, but it did help my focus a bit so I kept drinking it. For me stimulants have the opposite effect and are very calming and allow me to focus long enough to finish tasks. One thing to know: be careful when consuming caffeine while you are on them – I find coffee makes me feel awful mixed with adderall, but green tea has a positive energy-boosting effect. Also the first week or so of taking the meds might be a rollercoaster while your body adjusts!
