Omega 3/Fish Oil supplment side effects

Are there any Omega 3 supplements that won't cause nausea or stomach cramping? I took my first one this morning, with food, and 20 mins later I have horrible stomach cramps and nausea. I'm just about to head out on a 5 hour drive for the holiday so not too excited about sitting in the car with these cramps.  Not to mention my stool was normal this morning and now after taking one of these I feel like I have to run to the bathroom all the time (I've been completely fine otherwise before this).

So I'm assuming I just shouldn't take these? My functional doctor recommended them so I decided to try them, especially since I'm losing at ton of hair and my scalp is burning (I'm going to my derm for this but they aren't much help).  I'm going to have to take 1/2 codiene pill just so I can make this drive! :(

That's gonna be one loooooooooooooooooooong car ride eh! Ya, probably not a good idea to try anything new when you're planning a trip...I wouldn't keep taking them, once you get back hopefully you can sort it out.

Nordic Naturals cod liver oil helps so much and is just cod liver oil so if you can handle fish you can handle this and it has changed my life.
