If you are trying to get off amitriptyline, you are reducing it gradually, of course, because that is the safest way. But you will already be thinking more clearly, and your impaired memory will be improving. You're less thirsty, less constipated, steadier on your feet and less liable to faint, having fewer nightmares. Your breasts are becoming less swollen and less painful, your swollen face is returning to normal. You are feeling less bloated, your vision is less blurred.
There are so many side-effects of this dangerous drug, and they are so unpleasant and harmful - especially if you have been prescribed it in high dose - and the benefits from taking it are so few and, in my opinion, not worth the candle. You may find that the greatest blessing of all from getting off amitriptyline is that you will lose a lot of the weight gain that has been puzzling you. So you'll have more energy and feel ever so much better!
