I think the bigger concern should be forgetting what flushing is like after you've done them for years! I highly suggest looking into heavy metal chelation because metals do affect memory in the brain.
Regarding the weight- look into Iodine to correct any thyroid problems.
Regarding the flushing- I think you should encourage your daughter to do it with you. Look into Andreas Mortiz's version of The Clark Flush - which requries 1 week preparation with apple juice, stone breakers, omitting fat and meat, etc. I have found that the simple Liver Flushes that do not incorporate Epsom Salt are simply not as effective in removing liver blockage.
Try and remember what flushes you did and what they were like! :)
