Did you do a Colon Cleanse first??? With bloating and digestive problems, you should've done a colon cleasne NOT a liver flush. Are you having any bms/diahreah?
Why on earth are you drinking salt water? There's your 8lb gain and bloat.
Start by completley cutting out the salt. (and caffeine if you drink any). Drink as much water as you can. Eating a lot of watery fruits like watermellon could also help. You can keep drinking lemon water, just without the salt. Parsley is good for the kidneys and is a natural diuretic if you like eating that.
