Besides the meds, have you tried looking up home remedies for your tummy? Or even soaking in a hot bath?
Here's a few remedies I found after searching (although from the looks of them, well, they sound kind of weird. You might want to wait for your doc's script).
Squeeze a fresh lime and add rock salt and black pepper to it and drink this mixture. It will help soothe nausea. Alternatively sip limejuice with sugar.
A mixture of 1 tsp ginger juice (freshly grated) and 1 tsp of onion juice will help settle nausea and vomiting.
Another effective remedy is to chew 1-2 cardamom seeds. You can also chew 1-2 cloves if nausea is not due to acidity.
