Really good questions gettingbetter. As for me, don't worry it's no bother at all.
I think you're definately fine to take the probiotics and while not being 100% sure about the omega 3, i would think it is ok (and probably even highly beneficial) as the 1 gram of oil per capsule is such a tiny amount and shouldn't pose much of a digestive challenge.
I think i remember you asking in another post about the best probiotics(?). One really good one that i know of (and expensive) is called "Natren Healthy Trinity". It has 30 billion little soldiers including (i believe) 5 billion bulgaricus which is the third member of the trinity along with acidiphilus/bifidus. It is to be found in the refrigerated section of many health food stores. (this is not an ad :p). I believe they are about $55 for 30 of them.
