You did the right thing. Pdocs are brain chemists. It may take a while to find the right one for you. If you have bad side affects, make that call.
A tip to save costs, you may ask the pharmacy to only fill your script for a week or two at a time. [Split the script.] If it's not the right med, you're not left with a lot of pills you paid for.
Some meds take a while to build up in your system. With those, you may not notice a difference for a while. Often they will start you at a low dose and raise the dose until you are receiving maximum benefit.
Best wishes, and come back.
