Hi Bostonian,
Actually its not necessary to take exjade in the morning,i have been giving my daughter exjade in evening since she started exjade,you just have to make sure that you give it to her on empty stomach,and after giving it ,you'll have to make her wait for 30 minutes before eating anything.
I give exjade to her in water,just a half glass of water,and when its completely dissolved,according to my daughter it has no taste,you can also give her at night too,that way if she is experiencing nuasea,she'll sleep it off,lets say if she sleeps at 8,wake her up at 10 and make her drink it and then back to sleep,i remember Sharmin used to give exjade to her son early in the morning,like at 6 A.M i think,an hour before he woke up for school,that way he slept off the nausea he was experiencing.
Drinking too much water in morning sometimes doesn't feel very good,even to adults,so i think you should try evening ot night time,like if she takes a nap in afternoon,give it to her after that,or at night time.
Hope this helps
