Thanks guys, good to hear from another blood electrifying guitarist Steve555, and 2tuff, I think your idea is likely to be true, an extra BE bonus! I've been doing 2 hours a day for a week now- don't feel much different and no herxheimers yet (touch wood)but an enlarged lymph node near my ear that has been big for over a year has started doing funny things since I started BE- some days i'm sure it gets smaller and changes shape whereas other days it gets big again- i guess it's something to do with all the dead parasites being cleared from my system...
