Raynaud's Syndrome
"I&#039;ve been taking 2.5mg for a month with great results and no side effects, until the weather got colder so the doctor increased dose to 5mg, partly because he wanted a better result to my high blood pressure as well. The sudden increase has caused severe sleepiness and a tight chest. I cut back to 3mg for now to ease into it and will increase to 5mg if/when the side effects decrease. I believe in caution and I know my doctor takes the same stand."
