Re: withdrawal - effexor ...how long?? » Kim Hazell Kim ~ Slowly, but surely! Decreased the amount, added Kava-Kava in the morning, St. John's Wort at night, then started skipping every other day with the Effexor. One week from today I'll be off completely... I HOPE. It hasn't been easy. Yesterday I wasted the whole day in an exhausted daze. Today? It's still early... I could crash in an hour. Good luck! P.S. Read Natalie's post!
