Question/Comment:

I have been taking antidepressants for about 15 years now. In june 08, I had a quadruple by pass surgery and came out of it very good. Now, as I was supposed to go back to work on oct. 27 08, I was laid off and have been without work since. I had been taking Effexor XR 37.5MG once a day for about 2 years now and for the past month, my doctor went up to 75 mg on it and it seems that my body is rejecting it. It made me feel worst. So, I told ,y doctor that I wanted to stop taking it and he agreed with me and gave me back the 378.5Mg and he told me for the first week to take it every other day. It is so,so, bad. The withdrawing effects are so bad that some time I think I am going crazy. Is there some one out there that has taken this bad drug and kiked the habit and could speak with me. I need to know that I am not the only one. Help please!

Question/Comment:

I take Effexor XR, 225mg/day. I've been on this now for about a year, and it has changed my life. I think I've had depression for many years (undiagnosed, of course), and now that I've been managing it, I have been able to take my life back! I have made good decisions that have only helped me, and I can finally see all that I am capable of. Even if it's hard to get off of, I can only see the benefits outweighing the risks of withdrawal symptoms. I have forgotten a dose or two, and I have to say that my symptoms were not that bad. I have gone 12+ hours without a dose, and I felt a little light-headed, but I had nothing that I couldn't function normally with.

Question/Comment:

112.5 mg + Lamictal (250 mg) po sid for BP2

This medication has been great for me... effective and sadly the withdrawal symptoms were useful for getting me to take the medication on a regular basis (something I used to be horrible at), but f'in hell! The withdrawal symptoms are horrible! Even if I wanted to get off I'm not sure I would just so I wouldn't have to go through them. I once had to go two days and I just wanted to die the vertigo and out-of-body feelings were so bad. I had to sit as still as possible until my partner finally got my rx from the $%^$ pharmacy. I just KNOW when I've forgotten to take my meds during the day when 10 hours later the world starts to turn.

Out of everything, I just wish I had understood how bad the withdrawal symptoms can be before I started the medication. I will never touch paxil with a 10 ft pole considering the withdrawal symptoms for that are supposed to be worse.

With all that said, I'm grateful for it since I can be 'normal' on it.
