Yesterday I was out running errands, could feel myself getting more and more irritable and grouchy and anti-social feeling. I had a nice time being out in the lovely rainy weather, enjoyed the time alone, so that wasn't a prolem. When I got home I was short tempered with my sweet dogs who just wanted my attention, and had to work not to bite peoples' heads off. I realized I hadn't had any pain meds yet that day, although I wasn't really hurting that much. I took my usual half a Darvocet and a tylenol, and within half an hour the world was a much friendlier and brighter place. I guess I was hurting and didn't realize it. How strange is that??? Or is the Darvocet a calming agent as well, maybe? I can go a day without Darvocet if I am having a good day, so I know I'm not addicted to it. This has happened a few other times, so there is a pattern of some sort. Such an odd effect. Anyone else experience this too? I hate to think what I'd be like without the Darvocet when I need it!! Peace, Beth.
