Oh mama, hang in there, week 17 and still dealing with this is really tough, especially when you're working! A few of us went through the same thing, and the general experience seems to be that weaning too quickly is what causes that "rebound" nausea, so going slower than you think you need to is really the key, like stretching it out over a week or two rather than just stopping suddenly. One of my mum friends who was on the same medication found that shifting her timing slightly earlier each day (rather than skipping doses) helped her body adjust without the vomiting coming back hard. On the psychological side with the saliva and sour taste, that actually sounds like it might be a separate symptom called ptyalism, which some mums get on top of the nausea, so it's worth flagging that specifically rather than just assuming it's all tied to the medication timing. That said, since you've already had three unsuccessful attempts and you're still symptomatic past week 13, it's really worth having a proper chat with your gynae or KKH doctor before trying again, they can give you a proper tapering plan that fits your specific dosage and schedule, so you're not just guessing while managing work at the same time.
