Nicky,
I take 40 mg every other day. I am going to have a hard time if I start having major cravings. We don't have Tim Whorton's here in the US, is that a donut shop?

No my Neuro didn't say anything about taking a potassium supplement. I just found that doing some research online. I have read too that it can be dangerous to take the supplements. He did tell me that I needed to take at least 1,200 mg of Calcium daily to avoid weak bones and osteoporosis as I get older. Also told me to take Vit D daily. I bought a bottle of Os-Cal which has Calcium + Vit D in it.
