"i use to take 10 mg before public speaking/presentation in school and shakiness when performing certain medical tasks at work. i have high blood pressure, anxiety, shakiness during certain presentation tasks. my dr was concerned about my blood pressure sometimes being 158/90, usually when i knew it was going to be taken. after discussing with her i&#039;m now taking 60 mg sr, it keeps me stable without the peaks and crashes. i feel a little more energy physically because the fight or flight responses i felt were exhausting my body, although just not much will to get up and at it, and does make me feel a little lazy/apathetic/foggy, but my dr said it&#039;s still ok to drink coffee. and i feel not as irritable with my boyfriend."
