Dizziness, Headaches, Feeling Drunk Or Drugged And Sudden Tiredness/Sleepiness ? What Is

Dizziness, Headaches, Feeling Drunk or Drugged and Sudden Tiredness/Sleepiness. What is going on? The past 3 nights in a row, I ve experienced the strangest feelings, directly after I ve finished my dinner in the evenings.... 3 nights in a row now, so I m worried about it. I ve been geting very dizzy with a headache. I feel as if I ve been drugged or as if I m drunk . And whats strange is, I suddendly feel very tired. It s like I could just fall asleep that instant. I don t know if this has anything to do with it, but also the past 2 mornings when I ve woke up, I ve felt sick to my stomach and I felt like I need to go throw up. But never did. I ve never experienced these symptoms before. I figured it may be an issue with my blood sugar, but I m not sure if it s going up or down or what? Can anyone tell me whats going on with me? Someone who is knowledgable about blood sugars or has been through these types of symptoms before? I AM NOT PREGNANT!!! I just had a baby on 11/1/07 and I ve been on birth control since my checkup. Thats not the problem.
