Drive weakness effect of Amitriptyline

I took the amitriptyline for about 1 month. I switched from sertraline to amitriptyline. I am very tired at 50 mg and not really awake, in the morning I should take then 25 mg = 75 mg / day. If you already drive weakness has, it is difficult to get fit and become and stay. Now we try in the evening 50 mg amitriptyline retard and in the morning 50 mg sertraline. Sertraline is more drive-promoting. Promethazine I should take only when needed, but this is not necessary because I am sleeping very well from the amitriptyline. The promethazine has left in the effect and should have been steadily increased in order not to lose the effect , So I feel that. Unfortunately, I have increased from the meds and do not dare to drive a car anymore. Since the amitriptyline still does not help as it should, now the sustained release of it has been prescribed, which slows the release of the drug to the body. But about it I do not really notice anything and will definitely get another medication soon and can almost open a pharmacy and if that helps, the constant change of medis is also not good for the body. Concomitant symptoms of the drug amitriptyline: hearing voices, fatigue / impotence, weight gain, furry taste in the mouth, not driving with the car, pain, nausea, vomiting, digestive problems 24.11.09: that does not stop with the vomiting and diarrhea, headaches are not synonymous away.I probably can not tolerate amytriptilin. Let’s see what the Institute Outpatient Center is doing now. I’ll probably get another drug, duloxetine or again sertraline with promethazine and back to the neurologist for the headache. The question I’m asking now is the transition from amytriptiline to duloxetine if that’s so easy? Will also let my liver values check. Come before me, like a guinea pig. 2.12.09: From tomorrow I start with the Cymbalta (active substance duloxetine) 30 mg in the morning, instead of sertraline and amytriptiline. Promethazine for the night.
