I'm tired

I'm trying so hard to be good, but it's hard. Lately, I've relapsed and started up my stupid habit of drinking coffee at night after the children have gone to bed. For my husband, a late evening java is no biggie, just another way to quench his palate. For me it's a delightful treat that causes bouts of insomnia and results in my getting 5 hours or less of sleep. The first few days are fine, then my whole system goes haywire and I'm knocked off kilter. My biggest warning sign - falling asleep at my keyboard at work, something I did twice this week. The next is the inability to keep up with my exercise routine, keep up with my house and finally, keeping up with my kids.

So I've quit drinking coffee at night, but still paying the price. I can't stop yawning and I can't concentrate on anything.

I'm aggravated...
