Semi-fermented as Oolong tea it is, it still excites the stomach ache
if nothing in your stomach. So it's better not to drink too much green
oolong tea when you are in limosis or getting up in the morning, I
think its the same with green tea.But, for Oolong, I think if you drink
baked oolong tea, on the contrary, it still could safeguard and warm up
your stomach not matter you are hungry or getting up in the morning.
(The baked Oolong tea is similiar as puer tea, the reason it is not so
popular now is that people likes green colors (green leaf, light tea
soup, with beautiful vision enjoyment which people think they are green
food) and the "Yun" of Tie Guan Yin.So when you pay some attention to
the time of drinking oolong tea, it is really kind of enjoyment to take
cups of Oolong tea any time.The same time, Wuyi Mountain and Guang Dong
Oolong tea is still more heavy than Anxi Oolong in tea leaf color, soup
since they are more baked. So they are ok with your stomach. in
general, it is ok to drink any kind of tea any time, as long as you're
used to it, you can be used to it.It depends on you.

Thanks

Enjoy tea, enjoy life.
