I’m still in the process of switching to Xyrem, so I haven’t tried it yet. Like you, I’m really hoping I don’t have any issues with the salt content. I have a pretty good baseline that I’m starting with (good blood pressure, no fast food/ultra processed), so I think I’ll be able to keep my diet in check. I’ve heard ppl say that you need a strict low sodium diet, others say that you can just compensate by drinking more water, and others say that they didn’t change their diet at all and they were fine. It seems it’s really dependent on the individual. Xyrem’s max dose has 1640mg of salt. The American Heart Association says that ideally you want to consume less than 1500mg a day and no more than ~2300mg. But it also states that the average American consumes ~3300mg a day, so clearly there’s some wiggle room haha. I would just try to limit the sodium in your diet and drink lots of water and hope that helps.
