Advice & Tips: This is a very effective medication, but you have to take the full dose, and you and your doctor may have to fiddle with the dosage until you get it right. So far, I haven't really suffered much by side effects. I have experienced some dizziness, but it's not clear that effexor is the cause.
Cost: < $25 monthly
Side effects: heart palpitations, insomnia, vivid dreams
