Hi Farthan. Here are considerations- hope this helps!
1. One can find info on good anti-viral doctor John Chia by googling him. Some (though very few) of his patients were cured with antivirals. Though it is difficult to be his patient one can sometimes find a doctor nearby who can prescribe anti-viral for shingles/ chicken pox. I am not advising but this might be an option to consider.
2. Sometimes anti-viral drug therapy does not work. Sometimes it works partially but one still have retro active viral symptoms. Some people turn to herbal anti-virals such as equilibrant. Some people can't tolerate that one, but there also are great milder herbal antivirals.
3. It could be beneficial to go with methylation whether anti-virals work or not. I am basing this from my own personal experience and what I have read. Some people take herbal anti-virals with it.
4. I think methylation is part of a preventative good health plan, at least it has been for me. I think everyone could benefit from taking B12, preferably methylated, and methylfolate, or at least work up to it (many of us are not there yet because some sick people have side-effects in the beginning). This is just my opinion. Not advice per say.
Why B12 and methylfolate? Because from what I have read, these nutrients help our body express genes that help us detoxify and repress genes that are not beneficial. To the best of my knowledge, if one doesn't need methylation for CFS, the worst that will happen is expensive urine.
However, sometimes methylation can make symptoms of CFS worse, or heart palpitations or other side effects. Many people believe this indicates that one DEFINITELY needs it! But in this case, one may want to consider going low and slow to work up to it. (Many people who are sick with CFS also feel they benefit from liposomal glutathione too, and also lots of minerals).
From my personal experience, poor methylation and low glutathione= high heavy metals. It seems like heavy metals can precipitate all kinds of weird viral attacks! In my personal experience, the more that I methylate and detoxify, the better insurance that viral attacks and fatigue do not relapse.
I also think getting a genetic test to see which nutrients I needed has been very beneficial. I have a very good doctor who interprets the genetic test and helps with methylation and also treats long distance.
If my CFS started after chicken pox, I would have seriously consider anti-viral drugs first- only because of the success stories I have heard from people with CFS who in actuality had a mild form of shingles and were treated successfully with anti-virals. Hope you feel better soon!
