Anyone elswe told this about Clomid? (Same as TTC forum)

I saw my Dr about getting Clomid and he says that he won't prescribe it until I've lost some weight b/c it causes water retention so if (and I'm not so it was a pointless argument) you are trying to diet, it will push your weight up and might discourage you!

Sounds like a load of tosh to me but please, has anyone else been told this, is there any truth or was he simply fobbing me off?

HELP!
