There are so many threads about how much people have lost. I'm on the verge of giving up. I've lost 21lbs in 4 months but have had horrible side effects for most of that time. Feeling sick, suddenly being sick, sulphur burps, acid reflux and 24 hours of constant diarrhoea each week. Plus fatigue and constant coldness. I'm about to go away for a couple of weeks and just can't face being ill on holiday. Anyone had similar and got through it! I have 74lbs still to lose.
