Hi there, I am on the slow release type, 80mg a day. I found them very very useful in coping with the panic when it was at its peak though i don't think they are particularly great for my circulation - I have cold hands and feet at the best of times but I think its maybe a wee bit worse with these. Don't know if its my imagination but I feel a little bit out of breath on them sometimes too. Having said that, they really did help me when I was at my worst. I don't usually have food with them, or take them at a particular time or anything.
Take care
