My son has had migraines (that we now can look back and call migraines) since he was five or six years old. When he was about 8 we finally realized what they were, and he has used amytriptaline, gradually increasing the dose to keep them more or less at bay (we have referred to those as "breakthrough" headaches--meaning there always will be some, but we don't want to take so much of this stuff to completely block them but have the side effects you discuss). He's at 35mg now and doesn't get headaches very often. They tend to occur more during high allergy season.
