That's great that your MTHFR genes are normal. I've seen only a handful of people on here who didn't have MTHFR mutations.
However, if you're on this forum and investigating methylation, I assume you're pretty sick with ME or some chronic illness. So there has to be some cause, and it could be worthwhile to keep digging.
You could still have MTR and MTRR (B12 mutations). You could still have GST (glutathione) mutations which would lower your glutathione (the body's major antioxidant and detoxifier of chemicals, etc.). The best way to raise glutathione is to do a methylation protocol.
You could also have toxic metals such as lead or mercury which also impact the function of MTHFR (folate) and MTR (B12) SNPs - so basically as bad as having mutations there. In that case, you would want to chelate those out.
You can find out about B12 and glutathione genes by getting a 23andme gene test (unfortunately they just raised the price from $99 to $199). You can interpret that by running the raw data through GeneticGenie.org, and interpreting it with the SNPs Interpretation Guide linked in my signature link.
You can find out about lead and mercury by doing the hair metals and elements test used by the Cutler protocol and getting that interpreted by the Frequent Dose Chelation Yahoo group.
You can also do a methylation panel, which is a functional panel looking at how your body's methylation cycle is actually operating. If it's operating badly, then investigate what the cause could be.
There is the HDRI Methylation Panel which RichVank wrote an interpretation for, and the Doctors Data Methylation Panel which Ben Lynch has published an interpretation for -

Then also look at your history - have you been vegetarian or vegan, had exposure to chemicals, pesticides or toxins, had mercury amalgams, vaccines, eat a lot of fish, renovated old houses, etc.? Have you been tested for B12 deficiency or have many symptoms of that?
So as you can see, MTHFR is only one part of the puzzle.
