I asked about if this (7-8) was too much, after people here were suggesting it was, on Health Tap and what can happen if it is. The dr. that responded said it was a bit excessive and that it can cause increased heart rate and anxiety and that I should try to cut back. But I only drink that much when I am home 24/7 and have nothing to do but sit on the computer and watch TV. Or is my usual 4-5 too much too?
