i found that one can use grounding bands in place of the pads and sheets. The good thing about the bands is that they are more affordable, like $25 whereas a pad is around $115-135 and a sheet around $150 or so. I emailed some suppliers of grounding equipment and they told me that the bands just take a bit longer to fully ground the body but still do it. So I am going to go this route and continue to go to the park and walk around barefoot as that always helps.
