So honestly it has to stop, the caffeine, because it creates increased blood loss in surgery. It’s important the reasons why & you also can raise Your medical risks, yourself. Do it the right way, they should explain it (Diet and reasoning)way better with your surgeons, but we all could also ask ‘why’ as we go thru this. I’m glad you are asking tho.
In my opinion, Sauna and Water are your best defense in withdrawl, OR/AND start removing caffeine 3 wks prior to make it less concentrated and not immediate removal. Drink copious water to rehydrate yourself. Broad percentile of humans actually walk around dehydrated in life. (suggest: 1 gallon 110oz.) Hit the sauna and get a lymph node massage in your armpits,neck, etc. Push that toxin out with a medically helpful massage. Follow with water, to flush it out. It is not medically advisable to do greater than 15min 2x a day. Follow with a nice body scrub. Help those pores and clean yourself so they can breathe.
You are preparing for an invasion to your body with advance notice. I treated it as such. It helped me have the easiest surgery I could get for a 61BMI.
I know you will do great. Day 3& 4 are typically the worst you will feel into the pre-op diet. After that, your body is rid of ick so to speak. The pancreas stops sending out Insulin, and diabetics will actually feel way better at this point (if u need to, of course, raise your carrying of glucose gel or tabs for control, but no sugar on prep diet) The rest of us, will feel the flu symptoms dissapate.
