Hello dear @Notafanofduro
Duromine, like any other drug, has possible side effects. Mood issues are not the most frequent; however, it also happens.
Good news: most side effects disappear after the first week, rarely in one first month. If you experience it for a longer time, I'd recommend you contact your doctor. It may decrease your dosage. Usually, the lowes dosage of 15 mg has fewer side effects or doesn't have any at all.
What dose of Duromine do you take now? How long are you on Duromine?
