Easeful, I am going thru some really hard times with my son and his psychosis and we just got over a second hospital stay. All of this hit us in January, he will be 19 this year. I suggest that you go to
NAMI: National Alliance on Mental Illness and set yourself up a username and a password. I have been on that site day and nite and it will not only give you info on the different meds, but it has numerous different forums that are dealing with exactly what we are dealing with. You will always get a lot of answers to your questions and tremdous support and knowledge. Not that this site is not wonderful because it is, but this is the main site for people who are affected with every single type of mental illness. I really hope you go there. I am there all the time and my user name is Edsmom. Hope to see you there. Hang in there. Go there and someone will know something about the thyroid issue. I am praying for you and your son.
