Were you changing the dosage under the advice of your doctor? When you keep changing the dosage you can create other problems for yourself, because your body no sooner gets used to one dosage and it gets decreased or increased to another. An antidepressant isn't the type of medication that you can take more or less of according to how you are feeling. It's common to have to increase or decrease our dosage once or twice but not as often as you have. I would call your doctor and ask him what you should do at this point, and go from there. Then never adjust the dosage without the advice of your doctor, it just creates too many problems that you don't need. I hope this helps.
