When I stopped taking Venlafaxine (Effexor), the side-effects were immensely unpleasant. Brain zaps, panic attacks, hypersensitivity to light, barely any cognitive function. My psychiatrist was a sweet lady, but she did not appear to understand how tough it was for me. It boggles my mind she did not get it, she must have had so many patients stop with the medication, did she just not take any of them seriously?
In the end, I opened up the plastic casing of the pill, which turned out to contain a few dozen grains. Over the course of 2-3 weeks, I took a few grains less every day, until I was completely done with them. I don't know if you're allowed to do that, maybe there is no guarantee that every grain contains the same amount of medication? I'm not a fan of tampering with medication, but I didn't feel like I had a choice.
