First of all Congratulation Hyakula.   AS someone else suggested that Adua ko chya ( Ginger Tea) with no milk might do good for you as it helped me when I was pregnant.  Stay away form deep fried food, try to eat some dry toast with your tea that might help you.  I assume that you are in your first trimester right.  Usually second trimester is much better than the first one.  Other thing, I know we Nepali people love to feed someone we care about.  So, if your family is trying to feed you little too much than you want, politely deny it because it is all about you and the little one. 

Hang in there, Pregnancy will get better and all the best to you.
