When I took LDN at night, I slept 2 hours then I was up the rest of the night. I've read where you can take it in the morning so I did. I took .5 mgs at 6:15 am. About 2 hours later the jitters set in, which explains why I can't sleep at night with this stuff and now 7 hours later I'm still feeling it. Not horrible, just there. I hope this goes away by the time I want to sleep about 10:30 pm. I know they say the sleeplessness can resolve itself in a week or two, or it won't. Has anyone else had this happen to them?
