Thank you for dropping by and for your recommendation. Friends have suggested that too. However, I have resisted taking it because, I really do not like to take medicine and/or supplement. And no 2. I am not working so it doesn't matter so much if I am feeling tired in the day.
I hope this is only temporary. It was under control (most of the time) before my trip. So, I put it down to jet lag. Before the trip, I used to read for half and hour or more, then sit quietly and breathe normally for 15 to 20 minutes. I find that this helped me to sleep.
You might want to try it sometimes and see if it works for you.
Cheers!
