I have suffered from Restless Leg syndrome for many years. Eventually the doctor prescribed 2 x Pramipexole at bed time = bliss and a sound sleep every night. Now the prescription has been reduced to 1 pill per night because one of my other medications is not compatible with the pramipexole. Now I experience the jumping legs and arms every other night or when seated on a long journey. The worst time ever was an overnight transatlantic flight from Canada hours and hours when we were ordered to sit with seatbelts on (due to misbehaviour of a junior football team)
Churchill to be axed from British banknotes in the name of diversity.
Sometimes just some of the sounds available are enough. I hope you find something that works for you.
