I just started taking celexa 11 days ago, and I'm feeling some mood swings.

The past two days I felt calmer than usual, but today I'm back to the typical anxious feeling. Also, I find myself going from feeling good, to bad, and back to good in less than an hour. And I go from calm, to relaxed and peaceful, to sleepy and depressed in a matter of hours. All of these mood swings are pretty mild, but hard to manage.

Has anybody else experienced these ups and downs and leveling offs when starting antidepressants?
