Same here. I sometimes wonder what the hell is going on when I wake up with stomache pains in the middle of the night and then lets just say I get cleaned out. I stay away from green tea. It's just not for me i guess.
Here's a pretty cool abstract I found on-line. I'll have to come back tomorrow to explain the scientific jargon...i'm tired as hell right now. This study is a little off topic, but since it is sitting in front of me, i'll post it. If someone else cares to explain the abstract in more layman's terminolgy before I do, then feel free
Rudolf Locher et al. "Green tea polyphenols inhibit human vascular smooth muscle proliferation stimulated by native low-density lipoprotein." Eur. J of Pharm . Vol. 434 (1-2) 2002, pp. 1-7.
ABSTRACT
This study investigated whether human vascular smooth muscle cell proliferation induced by native low-density lipoprotein (LDL) is affected by green tea catechins. Furthermore, the effects of native LDL on extracellular signal-regulated kinase (ERK) 1/2 activity were determined. Cell proliferation stimulated by native LDL was concentration0-dependently inhibited by epigallocatechin, epigallocatechin-3-gallate, green tea polephenon, and the nonspecific antioxidant N-acetylcysteine (P<0.05). Combined treatment of green tea polyphenon and N-acetylcysteine markedly potentiated the effect of each drug on vascular smooth muscle cell proliferation. ERK1/2 activity was only partly inhibited by green tea catechins alone or in combination with N-acetylcysteine (P<0.05). These data suggest that green tea constituents inhibit proliferation of human vascular smooth muscle cells exposed to high levels of native LDL. Green tea constituents and antioxidants may exert vascular protection by inhibiting human vascular smooth muscle cell growth associated with hypercholestolemia.
If I remember correctly, green tea will increase fat oxidation but will also slightly lower testosterone levels (PLease correct me if i am wrong on this though).

MR. BMJ, as you already know, I was the one who had mentioned that a study showed a reduction in testosterone with green tea extract, but from further readings, this may not be the case. I found the full text of the original study and they INJECTED the catechins in mice and showed dramatic reductions in appetite and hormone levels, with ECGC being the most potent. But when given the extract or individual catechins, there was no significant effect, most likely due to the poor absorption or rapid metabolism of the catechins.
Another study looked at the availability of catechins from green tea and found the same thing, low bioavailability. From this evidence I don't think that green tea is going to affect hormone levels to any extent, and the studies on green tea extract show some impressive effects of the its components.
As for the best time to use green tea, I would suggest using it with every meal, as studies have shown it to reduce carbohydrate digestion and absorption, along with a thermogenic effect, due to MAO inhibition and caffeine.
