Burning pain in food pipe. Answer.

I am having a burning pain in chest since last 2-3 months. The doctor identified it as GERD after several tests including blood tests, ECG, H. phylori, etc and prescribed pantaprazole 40 mg daily for 1 month. However, after taking for 40 days and along with lifestyle changes like cutting off caffeine, spicy ,fatty foods, sleeping 3 hours after meal, having 5 separate meals,etc, I feel no major relief. Have now lost weight by 6 kgs in 2 months. Last week I visited another GI specialist who did an upper GI endoscopy and mentioned following in report : few white curdy patches in the food pipe,GEJ 40 cms, Lax LES. His diagnosis was GERD with esophagal candidiais . RUT for H phylori of biopsy was negative. He prescribed me fluconazole for 7 days, but no major relief yet after the course. Kindly suggest what could be the exact medicine for this. I appreciate a suitable answer.
