For myself Doxepin didnt do a thing.. while doxylamine succinate (sp?) was quite useful. It could well all just depend on the individual. What my doctor has told me that some can get tollerance issues with some benzos eg Temazapam.. after only 5 days. All this stuff depends on the individual and so one can tell you if you will get issues or not, so one really needs to weigh up benefits verses possible risks and if those risks are worth it for you. I think the big thing is if one does start to develop issues or these drugs stop working well (tollerence)... do not go and increase dose, continuing on taking in the same manner.
