That is a pretty decent dose.
You have the option of dropping it altogether if you don't need it for fertility purposes, are there's plenty of room to lower the dose.
I believe 250 IU's twice a week is or is very close to the minimum effective dose so you may have to tinker with it.
If anything, drop it for a month, see how you feel and if you're really wanting to use it, start back up slowly, maybe 250 IU's or so twice a week.
