Hi there....I'm a punjabi female age 45 years old....
my Ggt is 181 & it rised after I consume some slimming tea. I'm worried as I don't sleep well. I eat a balanced diet but its not improving.

Is feeling sleepy one of d symptoms?
How or what should I do to reduce my GGT?..
Does coffee really helps. I'm dislike coffee as it has high caffeine too.
Pls advise. Thank you
