Hi potty :)
Shouldn't matter if you take it with your fish caps, I take it by itself, I take mine in the evening sometimes with food, sometimes without (again, makes no difference)...reason I take it in the evening is because that's when I got home with it and I like to take things on a 24 hr time clock (same time everyday).
Keep us posted on how it goes :)
My bum is broken....there's a big crack down the middle of it! LOL :)
