clomid advice

Hello glow friends. I should be going on clomid in about two months if all goes well with blood tests etc. Has anyone any advice on how to take it and how best to improve my chances of successful conception? I've heard that clomid can make you moody and emotional, is this true? Did anyone who has had or is currently taking clomid change their lifestyle? For example exercise more or less, avoided certain foods and drinks or ate more of certain foods? Also did any of you get a fertility monitor? If so do you recommend it? I've seen the clear blue one for £120 and I'm debating buying it, would just like to know if it's worth it first.
