I was diagnosed with FD since I was 16. It's been 11 years. I went from taking different Antibiotic cocktails into taking accutane for almost as long. It does help specially when you start taking it but the side effects can be very severe like dizziness, Depression and anemia, dry skin and lips, nasal bleeding..etc though not permanent. Off late I got off everything and I established to myself that this condition is rooted in the gut. To save you time, hassle and money, I advice you to educate yourself about Candida as you will find that going on a healing protocol to kill the fungi and restore your gut flora balance is what's only going to heal you for good.
