Maybe all of them Since they all contribute to spinning the methylation cycle. It is likely that what you've experienced is a "side effect" of suddenly spinning it too fast.

If you're sensitive to B vitamins, and many people around here are including myself, you should probably consider starting with a very low dose of the basics such as B12 and folate.

At some point you will also be able to reintroduce the other Bs with the same technique. Low and slow
