Hi WindWalker,

Welcome to the forum! Years ago when I took trileptal I was told to drink lemon water because trileptal can cause kidney stones for some people. By drinking the lemon water it helps decrease any kidney problems according to my Epileptologist. Depending on how much lemon you want to have and the dosage of trileptal you take each day you should be okay but to play it safe check with your pharmacist especially if you are taking any other meds including over the counter meds. Here's wishing you well and May God Bless You!
