Hi, Wantabenormal! It is common for medications to start to have different effects over time, but this is something you should discuss soon with your doctor.

My experience is that they first go through a period of weeks to months of trying to find an initial therapeutic dosage of a drug or combination of drugs, then they later adjust the dosage aiming at longer term maintenance. And, of course, sometimes a drug stops working or never works at all for an individual, or the side effects just aren't worth it.

Please tell your prescribing doctor.
