Thank you all for your concern! This humble author is feeling much better today.

Yesterday, I Stomachache all day, and I was really touched by everyone's messages. Thank you all for your concern. I took norfloxacin, and I feel much better today.

Also, the weather has been unusually hot lately, so everyone should be careful what they eat. Food that hasn't been refrigerated should be thrown away after 3 hours, otherwise it's really easy to get sick... Sigh, I won't go on, it's all too painful to talk about.
