thanks Mrs. D, yeah I had tried to remind him. But he said i'm fine since I'm taking levocarnitine. For the ammonia, sure.. - even this I'm not 100% sure, to tell you the truth. And as for the liver, I guess it's a matter of time anyway.. with these much medications? When I'm not that young anymore then probably they will consider more aggresive interventions and hopefully they work so my not so OK liver will have a break?
