I've recently been on Effexor for over 8 years. The reason I started taking Effexor is cuze 8 years ago my Dr. told me I had a severe panic attack. These 'Panic attacks' would lead me to have seizure like symptoms where I actually passed out, twitched & convulsed. When I came to again, I wouldn't remember anything or who some people were. long story short, they put me on this drug, also with Clonazepam. It worked for a while. After a few years, weird symptoms would come back & they'd 'up' my dose. After just over 8 years my 'attacks' came back. By this time, they 'upped' my dose to 300mg. I thought they were crazy, but agreed to try. Nothing was working, I was having these seizure like attacks every 2 weeks & I have two small children to take care of! I demanded an answer this time! I needed them to run tests, try new meds, ANYTHING! I was desperate..I knew they weren't 'Panic attacks' They found something from results that were taken from my Cat Scan. It's called Septum Pellucidum & it's absent in my brain. I have no idea what it does, but if it's absent in someone's brain, it causes seizures! Yeah! They finally found the real problem..I have Partial Complex Seizures. I've had these all along. I have been on the wrong med's for 8 years now!! I'm on a new drug for seizures called Divelproex & it's awesome so far. I'm weaning my way off the Hellish Effexor. From dose 300mg to 187.5mg, it was good, than to 187.5mg to 150mg was good also. I went down from 150mg to 122.5mg & that also surprisingly was not too bad. A couple head waves here & there. I'm now going from 122.5mg to 75mg & that's been the hardest! It's been day 5 & I'm struggling. I know it will only get better once i'm completely off! It's just sooo hard right now!! I also wanted to add that Effexor can cause Seizures!! Please reply if you have any idea's that will make this better or just to say what you've been through.
