Update...
Well it's going well so far. Got an upset stomach which has put me right off food! Blessing in disguise!!!
1.5l of water down and got a cracking headache. At least if I have the headache now, it will be gone by tomorrow so hopefully will sail into ketosis as normal. Got no ketostix so can't be continually checking which is good!!!
Been busy setting myself lots of interim targets and joined a couple of challenges to keep me on track! x
