It sounds like you did the right thing weaning off very slowly. I have no experience tapering off from Effexor, but I do know it takes a while for your body to adjust to the condition of being without medication. I don't know how long you were on that med, if you were on it for a few years, then, your body would need at least a few weeks for the medication to be completely out of the system after the tapering off is completed. Sorry I can't be much help. I hope others can help you with this.
