Hi andy, try mixing shakes with ice in smoothie maker I use a kenwood one, it makes them taste mych better.
Painkillers, which ones if they were coated they would kick you out of ketosis! As SB said on a virtual empty stomach is most likely to cause an issue, I use paacetamol but not the caplets as they are coated.
Been to the dentist for your tooth? Uou need to give yourself every help and support you can, your loses are great, if week to week works for you, go for it. I set myself mini goals and am happy when I achieve them whether it is days or losses, its personal to you.
I bought a gorgeous top a couple of weeks aho in a 14, its hanging in view on my wardrobe, when I need motivation, I look at it, every morning I look and say soon!! I will be wearing it.
It is worth the effort, if you are able to handle the rest, putting it into perspective, what do you want out of this?
Hope you feel better soon
