"Antidepressant medication is effective for both seasonal and non-seasonal depression. Antidepressants have the advantage of not requiring you to get up at zero-dark-thirty to sit in front of a light box, but they too have side effects and may take longer to work. I tell patients antidepressants are like bodybuilding: You have to take them every day and results become evident in time. Moreover, if you stop taking them their benefits - like a bodybuilder's muscles - melt away quickly."
