Allergies

I jut don't get it, if I'm on allergy medicine, why do I still get sinus headaches? Last week one day, I couldn't do anything, yesterday I was fine during the day, took the kids to the dentist after school, I was so tired I just wanted to lie down and sleep on the floor, I didn't because it's really hard getting up from the floor whith my sore knees. I told the kids on the way home, it's left overs or cereal for dinner, I didn't feel like cooking, I went and laid down on my bed, and didn't get ip until 7:40 this morning. Only because I was dreaming about school, I thought I should see what time it was, which was a good thing, I woke up, both Joseph and Sarah had to be at the ortho at 8:20, and it's like a 30 minute drive, we ate on the way, needless to say. After the ortho, I dropped Sarah off at school and took Joseph to his counselling apointment, and the counsler says, you don't look so good Mom, I'm like thanks, that makes me feel better. Took Joseph to school then came home and even though I wanted to crawel into bed, I didn't I took some medicine for my headache and went to help the school nurse with vision screenings. Now, my head is better, but my nose is runny! UGH! I think it might be cereal again tonight for dinner.
