Any Green Tea Drinkers Out There? Please Read!!!?

I'd like to find out how long it took for people to see benefits and how many cups of green tea they drank---or, if they took the supplement, how many mg and how often(once, twice, three times a day?). I started this green tea because I have huge problems with cholesterol. My doctor told me that my body produces way too much and if this green tea regimen doesn't work then I don't know what else I can do because I tried just about everything else--except statins. So if anyone can let me know if they took or take green tea and if it worked or not, and of course, how long they took it before seeing results, I would be grateful. Thank you in advance
