Just out of curiosity, what pen/nib size were you using? I had a sample of it filled in my Lamy Safari with a 1.5 mm italic nib for about a week before I used it all. Every time I uncapped the pen it took a little while to get started, but I never experienced any flow issues on the level you did. I'm sorry to hear that...it's certainly an interesting ink.
Cross Verve with a medium nib. Very wet writer. I was surprised to have so much trouble.
