When your intestines start to heal, they can better absorb not just nutrients from your food, but medicines as well. Perhaps you are now absorbing more meds than you need?
That is a really good point that I hadn't considered. Before I went gluten free my doctor increased my lamictal dosage from 200 mg to 300, and today she wondered if that might be what was triggering this episode. She had me lower the dosage back to 200 and increased my anxiety medication a little as a temporary fix.
You've given me some hope now! I'm not delusional enough to believe I could eventually go off the meds altogether, but I do look forward to potentially decreasing the dosages. Yet another encouraging reminder that I'm on the road to celiac recovery.
