insomnia
"I took 3mg my first night. I was so groggy, I don't remember anything from about two hours before bed and I had the WORST TIME waking up this AM. I was so groggy and cranky and again can barely remember anything until I started finally getting up and around. This is super strong, I took 3mg, but for someone who goes days without sleeping, I'll take these side effects over no sleep any day. I am taking the generic. At least give it a try. I have to for insurance purposes and I'm pretty glad I did. My doctor says the grogginess will fade after a while."
