You can certainly change if it's not working for you anymore. However, keep in mind that the emotional stuff is something you might experience with any pill. This is because birth control pills, in general, deplete B vitamins, hence depression, mood swings, etc. Supplementing with a B complex vitamin helps, though. As for the acne, look for a pill that is low in androgens (male hormones). You can do a search on the web for some. Some examples are: Ovcon-35, Brevicon, Desogen, or Ortho-Cept.
