Try taking half. A whole one will give me an hour of two of good sleep but doesn't "knock me out". Honestly, I don't find unisom too helpful when it comes to my nausea though. :-(
Hey!! Gravol that will stop the throwing up...you said you dont keep food down so eat some crackers it works for me.
Try the chewing tums and buy some sea bands those things are magic i promise youll feel way better :)
