Hi Fazer, yeah GP’s aren’t really clued up on withdrawal or tapering off, well at least mine wasn’t so i know how you feel, but please dont worry about your liver, it will heal itself!
if you want to try cold turkey, its very bad in the first 7 days but you can taper off them by reducing say 2 tablets per day every week until your on hardly anything, the withdrawal symptoms wont be as bad then. every person is different though. plenty of water and get out when you can will help, i use the steam room and suana at my local gym which has helped me a lot recently
