I suffered with this when I first started SW too. To the point that I was having to lay down as soon as I got home from work, and not doing the things I would have normally. I did think about going to the doctors, but by the time I actually mustered up the courage, cos I kept thinking, ill give it another few days, ill give it another week, etc. then it just cleared up on its own. I put it down to such a drastic change in my diet. Hope you feel better with it soon xx xx
