We picked up on the comment from Margaret Mates, who wrote: " The CR version, when I take several doses in sequence produces a feeling of an awful heavy head" Heather, has had the same experience, but including a visual side. When sitting in a leather recliner chair, her head would leave a very deep impression in the back rest, and when she got up we would notice that the hair on the back of her head was greatly flattened. It was also accompanied by heavy sweating in the head region. Until we saw Margaret's letter, we had not realised that all of this stopped about the time that Heather started on Mirapex and reverted to non-CR Sinamet. Now, was it the change to Mirapex from Permax that did away with "heavy head", or was it switching away from Sinamet CR. Stay tuned for the next episode of "Mystery" SEASONS GREETINGS TO YOU ALL!
