Blood pressure, blood sugar can all drop once you are on CD. Could also be a virus? Are you feeling unwell apart from this.
It could be you went too long between packs or water or that you got up too quickly, postural hypotension.
You are on SS+ at the moment, you haven't forgotton to have any of the packs?
Looking at your BMI, I think its time for you perhaps to move to 810 for a week or so then start moving up the plans.
Have a chat with your CDC.
If you still feel unwell tomorrow contact your GP.
Hope you feel better soon I know its scary when something like this happens.
