Anybody had any side effects from Effexor? I forgot to take it about a week ago and just didnt bother and I have had NO side effects what so ever. I am wondering if it is too soon or i just skipped it all. You know what i did find out though.....i was given massive very potent pain killers for several YEARS after a massive car accident, and it was the hardest thing to get off of and i would get off of it then go back then off and then on and it was a terrible terrible experience but i found that it was mind over matter. If i just knew i had the pills in the house then i was ok, but i would start to freak knowing they werent available and i would work myself up into every single symptom going and finally end up in emergency. I took quite a toll on myself. But dont dwell on it if you can. Think about doing something else and dont let your mind wander. Listen to the radio at night until you fall asleep....anything but dont dwell on it!
