"i&#039;ve been on ambien and it was too strong. it gave me brain fog the next day. taking half a pill helped but i did not like that it was habit forming. got some samples of silenor 3mg and it helped keep me sleeping or if i woke up i would go back to sleep. i only take half a pill with an 8 oz glass of water and that does the trick. it also helps to use earplugs to keep out noise.  ive noticed that some people complain of weight gain. i cant imagine how that could happen if you are sleeping. but if im awake and nibbling in the middle of the night, unless i up my exercise it&#039;s to be expected."
