Stilnox symptoms and conditions

Hi ! I'm French and bipolar 2 rapid cylcing (every 2/3 months for about 3 weeks each taking anafrani)l. I'm 50 years old and I had lithium for many years. Since July I have lamictal. It's very recent in France and my doctor doesn't know if my problem to sleep I get since I have lamictal will go away or not and if lamictal is responsible.
I describe the problem : I have difficulty to get asleep, I wake up during the night and I wake up very early in the morning even if i go to bed late. So I'm obliged to go to bed before 10 pm. It's very hard but since I take lamictal I had no down since September (6 months it's wonderful for me)
I only had some variations during the day at the beginning but it seems to be better. I feel really better than with lithium. But there is this problem of sleeping. In France nobody could answer to me and my doctor told me to go on internet with USA of Canada where you use for long time lamictal. Do you know something about that and do you know if it can be better after a few month more ?
Could you please answer me here or on my email : ******
Thanks a lot in advance and sorry for my bad English. I hope you will understand me.
Kind regards
N.

This is a follow up message to 'Marika''s message; I took Stilnox on and off 2 weeks ago, and then there are some unwanted side effect which arrouse my attetion of finding more about Stilnox (ambien) side effect. I had experienced S +S of peptic ulcer which strong acid reflux occured before and after I took the meal. Also, I had noticed some irregularity of my heart beats. Four days after I stop taking it, the S+S started to disappeared and my stomach is starting to feel at ease. Is there any possibilities which we might have the chance to understand a bit more about the pharmacodynamics and safety features related to this medication.
Man!! the upset stomach really upset me...
