Welcome belly, I am on my first week of step 2 after stepping up from 1b and losing 16lbs, my weigh in is later today so hoping for a small loss! I still wobble sometimes and I have sometimes achey legs and also very very hot feet, I put it down to my age tho lol, but would stress to drink at least 3 litres of water or 4, this could help, you can will succeed, now headaches out the way keep focused and look forward to hearing your weigh in on Wed, good luck x
