Had insomnia all my life, now in my 40s. Took 50mg and seemed to be the miracle sleep pill I was looking for but stopped working after 2 weeks. Doc had previously told me to up the dose to 100mg after 2 weeks anyway, which I did, but still not working. Has this happened to anyone else? After feeling good for 2 weeks I am now getting anxious about insomnia and feeling wrecked all day again.
