Well yes, a) ADs can do horrendous damage, but

b) very often, much of this damage can be healed in time with the right diet and supplements.

I belong to an internet list that is run by someone who has been helping people in this capacity for 23 years. She has been helping me. It is a slow process because I stopped my AD cold turkey, which in tiself can do a lot of damage. It's a shame there aren't more people like her around to help, ADs are now the most commonly prescribed meds in the US.
