Has your GP referred you to a psych/CPN or even for counselling?
Girlfrommars - It is ok to take while pg, although it hasn't been around for as long as some of the older ad's (only about 10 - 15 yrs) so if you are not likely to be pescribed it for the first time if you a pg, but if you are already taking it it is safer to continue taking it rather than risk altering the balance by taking something else (was told this by my consultant and cpn)
