Hi Samantha...did you drink LOTS of water before your flush? And did you drink lots the day after your flush to rehydrate your body? If not...start drinking warm water now...2 litres of it.
Chewing on ginger or ginger tea can help with stomach problems.
Did you have diarrea enough to get out all the stones? So they aren't still in there seeping their toxins into you? Hope so! If not take another tbsp of Epsom Salt in water. (but remember to drink MORE water then too)
