@Charis1213 , i'd say the paracetamol was having an impact, so that's a GOOD score.
I'd also say the difficulties sleeping probably have an accumulative effect over many days, so that would account for some of the numbers.
And
@SB.25 I would suspect, that your body is confused by the low figure, and needs a little time to adjust itself to the changes your making.
I know when I lowered my carbs and sugar I wasn't testing at time, but I did feel wretched most days...something to do with the body craving carbs..(sugar addiction likened to drug addiction in some posts )
Sure if you can suffer it in the short term, the long term looks a lot brighter.
Hope the numbers tumble and that sick feeling passes soon.
