Listen to mammo's advice.
In your case withdrawing from medication may be best under the supervision of a psychiatrist -but one who is interested in doing psychotherapy with you and not just drug maintenance. Keep in mind that the physical and emotional side-effects of medication withdrawal can vary sig. between individuals. You sound like you want to take charge of your life -have a look at www.mypersonalities.com for self therapy.
If you can go without it, then it is def the best choice to stop...I would decrease it by small amounts every 4 to 5 days...if that doesnt work...decrease it by small amounts for a week then decrease again for a week etc...Good Luck ..its not an easy task but well worth it!!
You should only do this under the guidance of your doctor. We're all different when it comes to these medications and withdrawal. Plus, we have no idea what your health history is, so ask your doctor to tell you how to wean off and what to expect.
