If you're on CD1 you can start taking it 3-7, 4-8 or 5-9... when do you normally O?
My suggestion would be to take it from 5-9 to get an O right around CD14ish, when I took it any earlier the odd thing was my O would move back.
The first cycle I took 80mg's then bumped it up to 160mg's... you could start on the 160mg's if you're really trying to get instant results tho I've read many women starting at varying doses from 80, 120, 160 (even more altho I wasn't too sure I'd go higher)
I noticed things like nausea, headache, emotional and stuff but it wasn't every cycle either that I got side effects. They weren't THAT bad either. Altho one cycle I dipped pretty low emotionally, but I think that had allot to do with EDD's and finding out about my lost tube etc...
I'd suggest trying Geritol and lemon water too, it couldn't hurt
Any more ?'s ask away and I'll try to answer them when I get home from work tonight
