how is your mum?
well, i still think all pills have some "unnatural ingredients" i.e. even if Valerian pills are made from natural herbs, but the "cover" of the pills may not be natural right?
i don't drink much coffee, and never at night. I did drink tea at night ever since i was a kid. But this habit was changed after I started to drink the "black bean tea". Thanks for the suggestion, may be I need to open my windwo more
thanks for the news of wave, I wish to see her soon
