i used one on each foot and actually only slept for 4 hrs before having to get up for an apptmnt. there was dark goo on both pads almost like gel with more on the right foot. i had to take a soapy washcloth to get the remainder off my foot. i had a headache and had to urinate frequently. drank a ton of h20 and feel better now. this is pretty neat!!! anyone have similar experience? what does that dark color mean? can i use the pads under my arms for lymph/aluminum detox from years of deodorant? i heard someone pasted it on their liver - will that help too? i start chelation in 1 week. they've been prepping me with other iv's for a while now bcse i could handle only 1/2 bag every other week i think it was, and now it's 2 bags/week but haven't started yet. i think the pads are really going to make this easier for me. i'm excited. thanks dr vinograd. your staff is very efficient and helpful as well.
