I'm trying to reduce and come off them Rog, because of my doctor saying "do you need to take them?"...
That got me thinking of trying to come off them by gradually reducing the intake - because of what he asked *although not actually advising me to OR how to*. When I see him next I'll mention what I've been doing.
I'd rather you went and discussed it with your doctor and said you want to *try* to come off them. Dropping from your present dosage, what? 40mg day (2 x 20mg capsules?) would most likely be too much to reduce by trying one 20mg a day.
I went to 10mg capsules so I could juggle the amount if I felt I needed to; 1 x 10mg or 2 or even a third so 20mg or 30mg for that day if it'd been a bad one.
If you want to try to trial reducing and see how it goes before seeing him you'll be able to tell him what you've tried and, probably of more importance to you and him, how you've managed trialing the reduction over X days/time period.
BUT... speaking to him about reduced dosage capsules so you can manage a gradual reduction better would be what I'd do - and advise you to do

. *Stressing wanting to come off the damn things*. Fingers crossed for you
