ya once in a while I have this problem.
If I drag on, all the more I cannot sleep. Cuz when not enough
sleep, you will get very tensed up or your brain becomes very
active. All the more you get insomnia. That's when sleeping comes
in handy. Usually just need to take for one to two nights to adjust
back to the normal sleep routine and relax the body.
As long as you don't take this medication often, the normal GP are
more than willing to prescribe the medication to you.
