I took my first prescribed dose, and it felt like I drank 20 cups of coffee, and the effects lasted all night and the next morning! It also made me enormously irritable and grouchy, not to mention I did NOT get one minute of sleep all night, and I took my first and only dose at 6 pm, early evening. What is worse is that my doctor basically called me a liar by stating he's never heard of that happening when I told him about my reaction. He also believes this drug is better and safer then hydrocodone! He said that ultracet is not narcotic, which is not the information I've found out about it.
