I've been on Cymbalta 60mg for 2 months now (30mg first month) combined with 50mg Lamictal for depression, anxiety and possible manic depression, with no positive results, only negative side effects: fatigue, insomnia, oversleeping, weight gain. I also take Adderall XR 30mg. Ever since I started Cymbalta I immediately began to feel zero benefit of the Adderall! Can the Cymbalta be counteracting the positive effects of the Adderall? (I've been on Adderall for 4 years) I feel like the Cymbalta is preventing the Adderall from working. I'm considering going back to Celexa because of this. Has anyone else experienced this? Thanks.
