Lol, I ain't too good either at the moment, but I was already a bit depressed for other reasons, but Clomid made it significantly worse, sometimes I get in a terrible mood for no reason at all, it's so weird, I just can't seem to smile or even look neutral, I can only look unhappy and pissed off. I get upset at virtually nothing. Even the tiniest problem can ruin my day. I only have 4 days left! I guess I should start to feel better in a week then. Hang in there bro.
To answer your question : no I don't seem to notice any difference when taking it at night or in the morning and it makes sense cause Clomid has a long half life (5 to 7 days according to wikipedia and I remember reading something like 3 days on bodybuilding forums).
