Hi Paula, there is no shame in having a chat with your GP or practice nurse - we all start off on the lowest dose and then have to amend as/if times change. I was on 1mg for 2 years and then some night sweats started again so increased to 2mg. Are there any external stresses which might be affecting you?
I guess if you feel you can manage, I would wait and see if it settles, if you work for example and need the sleep then you might want to ask about an increase.
