a friend was on Levlan, and every single month, three days before AF she would break up with her DP over the most ridiculous of things ... I'm talking yelling and screaming, throwing engagement rings and cups, packing bags and leaving ...

and 1-3 days later, sanity would be restored ...

after about 8 months, she realised the link to her pill, and after trying to "contain" herself the next few months (unsuccessfully) she just ended up going back to her Dr, and getting a different pill which was based on a different hormone ...

solved!

but it took a while, and I think she ended up trying 3 different pills, to find one which didn't turn her into a batpoo nutsoid killer lady.
That's exactly what happened to me when I was on Levlan. I was a mad-woman. I kept packing my bags and then I'd be fine. I'm off it now and I feel heaps better.
