Doing the BPs with the MC you are basically turning the MC into a colon cleanse. Because of the highly absorbptive nature of the BPs unless you are being really judicious and doing the BPs at least 1 hr before or after any lemonades and in addition your are drinking lots and lots of water you are robbing yourself of the nutrition and cleansing properties provided by the lemonade components. Just making this clear for other folks reading this.
A day or 2 days later certainly will not be the SWF you're passing. If you haven't eliminated the SWF within 2 to 3 hrs max you are absorbing the salt which very likely is caused by dehydration which is quite possibly caused by the BPs high capacity absorbtion rate of fluids. The BPs work best when eating regular and drinking lots of water. The 1 hr before/after rule with the BP also applies when eating regular.
My routine that works for me and has also help many other is 1st thing in the morning upon arising drink 16 oz of plain water to make sure you are hydrated. 1/2 later drink the SWF then 1 hr later drink 32oz of plain water. For most folks the SWF doesn't start evacuating for 45 min to an hour and then usually takes 2+/- hours from it's ingestion to get it all out.
