Hi Lin
If you had signs of the estrogen running out in late evening / overnight then going down to 1mg is not likely to help.
If you find that 2mg is stopping them all day till evening then there are other options.
Get your doc to agree to patches sooner as they will give you a constant feed all the time your wearing them.
If you don't want patches then you need to add another 1mg of estrogen in later in the day - ie take your 1mg conti in the morning at 8am and then another 1mg estrogen tablet at 8pm.
This would balance the 2mg more over the day in either case.
The trouble is convincing the doc though as patches are more expensive and the 2nd 1mg option (elleste solo for example) would be another prescription.
Its really up to you though and you need to make it clear that 2mg was originally working.
However after a while our bodies get better at processing what we give it. So we either need a higher dose or spread it out more.
In your situation spreading out the 2mg of estrogen during the wider day would hopefully give you more lasting relief (and better sleep)
I'd say if the 1mg is not enough then you should start to see sweats/flushes move into the late afternoon and early evening unfortunately.
Hope you get back for another option soon.
