I started Amlodipine two weeks ago and it didn't go well. I suddenly felt tired, angry...very angry and suddenly depressed. Despite what some of you might think of me...LOL...I'm the type of guy that talks, laughs and jokes with people where ever I go, so this was really uncharacteristic of me to feel like this. I only used it 4 or 5 days and then stopped. I'm feeling much better now. Has anyone else had any or all of these side effects from Amlodipine (Norvasc)?
