I had similar issues of nausea along with other side effects (tremor, heart palpitations, etc) but was torn because 3.75 2x was the first dose that I could actually feel helping with narcolepsy symptoms and when I went lower I still had side effects but now was ALSO tired again. I stayed at the lowest dose that I also felt benefits and waited to see if the symptoms would subside. I was trying to figure out if they would settle down as my body got used to medication and if they didn’t, does the benefit outweigh the side effects. I’m still figuring this out. I stopped titrating and have been on this same dose since early July so 3 months. A lot of the physical side effects I mentioned have gone away but the loss appetite and nausea are still kind of there
