A low fodmap diet is the most difficult diet ever. But you can purchase fodzyme from Monash university in Australia and put it on your food. Doesn't work on polyols but still not bad. I did this for six months along with Atrantil and megaspore biotics. Watch probiotics. Some are worse for SIBO. I have methane, the worst, and my score was 71. After six months of fodzyme and those supplements my score dropped to 54 only so I took the xifaxin. I'm on 2nd round. SIBO is very difficult to get rid of. Now I've added kirkman biofilm defense because SIBO warriors build protective shields. They are insane bacteria that fight to kill you.
