My 9 year old son has major problems with sleeping. He started on 3mg, then 6mg and now his specialist has upped it to 9mg. How long does it normally take to work and how long does it stay in the system? He always struggles to get to sleep and then always wakes up every night at least twice/three times a night. Would it be better to give him 6mg then another 3mg if he wakes up or give him the 9mg?
Thanks for your help.
