"i just started on this drug 2 weeks now. my doctor prescribed it to me to help deal with my concussion headaches and to help me sleep. the pain-free aspect is quite lovely, however 2 weeks in, and i&#039;m suuuuper groggy. it doesn&#039;t help me sleep, but i didn&#039;t have a problem with that - it was just the post-concussion headaches. my doctor&#039;s main goal seemed to just send me back to work. i&#039;m glad i didn&#039;t have to drive into work today because i&#039;m not sure i&#039;d be up for morning rush hour traffic. she only prescribed one month&#039;s worth (10 mg pills) &amp; i can&#039;t wait to be finished with it. i have noticed a large increase in &quot;chubbiness&quot; around my mid-section. i notice that some weight gain is one of the side effects as well."
