I am sorry that you have this symptoms, I am also having the same, nausea day on and day off, and some times wake me up, I am on anti-nausea now 3 times a day, I also have more saliva after meals and woke up with my mouth full of saliva,my tongue with white layer, spasms deffirent palce every day mostly my right side.
It is annoying I know but we have to give it time what I see its getting less and less, Even with those symptoms worring will not get you anywhere, try to be bussy I try to work more and ignore your thoughts try for couple days and you will feel relife.
