Yea I always get urges to just stop my medication because I feel that I don't want to have to rely on pills to make me happy my whole life. But if the medication is working for you and helping and not hurting I would advise to stick with it. Whatever you do DON'T just stop it cold turkey. Make sure to talk to you doctor first.
I have done than before and believe me it not a fun thing. You mentally feel like you are losing your mind.
If you don't think you need the Atrivan make sure to talk to your doctor first about getting off of it. He/She will most likely gradually lower your dosage.
