ADHD in my life

I have a son who has Adhd/Aspergers/depression axiety.  I had him on add meds for 5 years. If I can tell anyone on here anything please stay away from these meds as your child is growing and forming of their brain.  I truly feel it has morphed my son into someone I don't know.  He has so many health issues now because of the meds and the dr agress that the add meds has caused the anxiety/depression.  which means he is on lexapro.  his most recent label on him is cyclic vomiting syndrome.  its really terrible.  and I feel that the meds caused this.  We never encountered this issue before the meds.  now he is horrible effected by horrible bouts of vomiting for days on end.  my child was the picture of health until he started these meds.  and within 2 years he came down with everything. was in and out of the hospital because the lymph nodes in his bowels would swell and he would become very ill.  I know to each their own about the meds but if i really thought what these meds would have done to my still yet forming son I would have chosen other means of educating him.  now he has a tutor in school for 3 hours and can not longer attend the class because of his anxiety.  i wish i could get back my little boy who used to love and feel close to us.  at the age of 11 he is no longer loving depressed and sick as a dog.. i am not saying the meds caused the cyclic vomiting syndrome but i am thinking we never had this problem before the meds.  thanks for reading!
