No it doesnt matter on clomid.
Take it all at once. It has a long half life so as long as you saturate your system good at first you'll be fine.
Some guys like to take 200mgs the first day and then start the 100.
I dont know how long of cycle you have been on but what you posted up works well for me. 100, 75, 50, 50.
I also do exactly the same as you mentioned on the aromasin. 25, 25, 12.5, 12.5.
You should be golden.
I have read many things about clomid and from what I have gathered taking higher doses does not help and only may cause more issues with visual sides and moods.
