It's been about three weeks since I started using and ......AMAZING, truly. Back in 2018, I fell downstairs at home, after which my feet became numb, I could go into detail but we won't. Since I started using, the numbness has decreased, not back to normal but getting there, also my sleep pattern has improved, I'm sleeping for longer and thus feel more refreshed on waking. If it continues at this rate maybe, just maybe I'll feel twentyone again....Yeah Right. Many Thanks from a retired Trucker (74 years young) before I go, I have been singing your praises to all and sundry. My Thanks again, David Lloyd Bowen.
