Hi Ruby,
It’s amazing that you’ve managed to cut down to just one tablet. You’ve done so much hard work already. I would cut that one tablet out, you will feel crap for a week but your so close already that I would just go for it. Maybe pick a time where you don’t have much on and go for it. You can do it.
My tips would be drink loads and loads of water, have a hot water bottle for the restless legs, take vitamins and keep coming on here as talking helps loads. Theses guys have got me through it
