Guru if in doubt ring your gp for a chat. whats the harm? you've got a history of DVT so i betcha the do a blood test to check your clotting levels. it'll put your mind at rest.
I'm worried babycake that if they do that he'll just say "oh it's that diet, you'd better come off it." Which is what happened when I was on LL and got terrible stomach pains. The docs made me come off it.
Turned out I had cysts on my ovaries but didn't find that out for another three years because they just blamed the diet.
I would have told them to test me for everything else before I came off the diet! Just goes to show you how arrogent doctors can be sometimes!
(sorry they annoy me when dealing with these diets as most of them haven't a clue and for all their education they refuse to get a little more!).
