Yeah, 50-75 mg dose knocks me out within a couple of hours. On 25mg at 9:30pm, can't get to sleep until after midnight and still wake up sometimes in the night, then it's really hard to get oriented in the morning. People say that once you get past 100 or 200mg it doesn't have the zonking effect, but I doubt that. I think it varies person to person. If I had to take it during the day I couldn't function. See if you can get a daytime pill that accomplishes a similar result.
