So 18 days ago you were on your eighth day? That's great, hope you are continuing even if not posting here.
I'm on day 2, hope to continue on, so far not having any problems. I was hungry this morning but I got busy at work and forgot about it so it's all good. :p
Went out to lunch with two coworkers and just got back. I drank iced tea, told them I didn't feel very hungry but didn't mention the fasting, just that I wasn't up to eating so I just sat and drank my iced tea and nobody cared.
