First dose, First round, Clomid

Hey y'all. My husband and I have been ttc for the last 3 and a half years. We have a wonderful healthy 7 year old, so this is hard for us to understand. Anyways, I am scheduled to start my first dose of my first round of Clomid and I was wondering if there were any other who have tried this and their experience with it. I have heard it's best to take it at night. Does this matter? I have also read there are certain foods and beverages to avoid while taking this. Is there any truth to this or? Thanks in advance. Any advice and/or experiences are welcome. :)
