Upset Stomach

I have been having upset stomach for a couple of days. It could have been caused by too much food in the Chinese New Year, or more likely the watermelon fruit juice that I had prior to feeling unwell. I believe many people are likely to gain weight amid the festival season, probably caused by too much consumption in “Rou Gan”, “prawn crackers”, “chocolates” and other New Year junk food. I have yet to weight myself but an upset stomach could probably avoid the likelihood of having a diet after the New Year.
