I recall reading here that a lot of people don't start to recover until 6 to 12 months because it's only after that much time that they are sick of being sick so they start to treat themselves properly. Sounds like you fit into that category...

Someone can help you better with the vitamin supplements or you could easily search for that info on this board. Quiet rest is important. Stop drugs and alcohol. Eat a healthy diet. And figure out what is making your symptoms worse (TV, driving, working, etc.)
