For over a year I have been taking excessive amounts of Benadryl. I am addicted to it and now dependent on it. I've searched online for answers, and generally what I find is people asking questions like "How do you get addicted to Benadryl?" I believe I use Benadryl as a way to numb my emotions and space out so I don't have to deal with life. Generally when I take Benadryl, I start spacing out, and don't feel sad... I just feel numb. I am preparing to stop taking it, but I am concerned that I may have already done damage to my body. Obviously since I've been taking it for so long, I've had to up the dosage to feel anything. Last night I took over 20 pills and my vision got so blurry I couldn't read and I was seeing things. Does anybody know the long-term effects of Benadryl? I know it can mess with cognitive function; it's already affected my memory. Any information would be greatly appreciated.
