How you react after having treatment is just as important as how you are before.
If you are on any medication, you can’t have the treatment. Antiobiotics and any other medication change the way your body reacts, so lying about it doesnt help. The toxin simply won’t work properly, or won’t be as effective.
Afterwards, you need to remain upright as the toxin will diffuse and spread out to areas which it isn;t suppoosed to.
