I'm not familiar with Oleander Soup so I can't say much about that.
However I've been using the Complete Bob Beck Protocol for almost a year now and have some actual experience. I don't keep garlic or onions at home but if I go out, especially at Asian restaurants where they load up on both I'm not picky. I'll eat it all with no adverse effects.
I use the Beck Protocol first thing in the morning when I wake up. I take herbs, drink herbal tea and drink coffee while I'm using the protocol. One thing I did notice is I can't drink as much coffee as I used to because it makes me feel crappy after about 12 ounces.
When I use the Blood Purifier I make sure I haven't taken any aspirin, ibuprofen, medicine or alcohol while using the device but once I'm finished with my 2 hour session I have no hesitation taking them and have never had any adverse effects.
The Blood Purifier is, in my opinion, the most powerful of the 4 parts of the Beck protocol. It can really kick your butt if you are not careful due to it killing off pathogens in great quantities. The only problem with the Blood Purifier is it only cleans the blood. If you have a virus in your lymph system or nerves it won't get the job done.
I own the Sota Magnetic Pulser and use it twice as much as the Blood Purifier but have come to the conclusion it is not powerful enough kill viruses. Maybe suppress them but not kill them.
I am currently looking at the The Klemens Super Magnetic Pulser and the OMF Generator to address this problem.
