That's way too high of a dose. You are going to get terrible side effects from those doses.
Clomid never needs to be dosed higher then 50mg but is best dose at 25mg because of its 5-7 day half life.
Nolvadex never needs to be dosed higher then 20mg. However I do remember reading a study somewhere that showed nolvadex had no greater action at 20mg then it did at 10mg other then an increase in side effects.
Hope this helps
