That morning sickness sensation is overnight dehydration. I know of some who had that and got into a habit of waking up in the night to drink some water (kept glass on nightstand). Another just woke up a few minutes earlier and drank some water, then waited for it to kick in before she got up.

Since you just had your DS about 6 weeks ago and you're now only 5-10 pounds from goal, you need to start adding carbs to help slow your weight loss. For me the weight loss slowed as I naturally started to eat more and add more carbs the farther out from surgery I got. It took me almost 10 months to lose all my excess weight but I had the DS in one stage. You probably need someone who was a two parter (VSG first then the switch later) to answer your question directly.
Check with your surgeon before resuming your exercise, since you did just have MAJOR surgery less than 2 months ago. My surgeon had me weight approximately 4 months before I could exercise. Ironically when I exercise, I do it not to lose weight but to tone muscle. Don't do any cardio - you don't want to burn calories because then you'll simply have to replenish those burned calories. My "cardio" amounts to walking 1 mile on a treadmill.
Can't help with the morning sickness question but seems like Val had the right answer for you.
