my inlaws recently forbade me to drink ribena too frequently. haha. They say its too "cooling", maybe that's why you have phlegm?
dont't really like those packet ribena, find it abit sourish. I have a sweet tooth, so doc advise me that its alright to eat sweet stuff, but not the whole lot at 1 go. Thus hubby is now rationing my Amos Cookies. haha.
Do you feel faint most of the time or when you bend up / get up and down too fast? Perhaps you can also try to take in more fruits? Fruits also have sugar in them.
