Wyeth Pharmaceuticals in the package that Effexor  be  slowly tapered off at the rate of 75 mgs per week.   If are mad at the company you can report  side effects to the FDA  at 1-800-FDA-1088 . The feeling of electric jolts to the head  comes with tricyclics as well. Ibogaine is rough on the body as well as the mind. I don't have the exact quote at hand but I recall that Ibogaine is described as MAOI   with regards to serotonin and  I strongly believe that combining a SNRI with iboga is risky  without a 2 week washout period  . i have not typed letter in years and i could use a night  of sleep so the spelling  sucks.  I am looking info on SNRI withdrawals and iboga. Best wishes  .
