Hi, I'm new on here. Not sure if I'm posting this is the right place but here it goes. I was wondering what you guys have tried as far are medications, herbals, etc. I'm pregnant right now (14 weeks) so I can't take much of anything right now. But I do have an on going problem with low Bp and a high pulse rate. My bp also will drop 20 points when I stand up. Because of this, after doing some research, I was thinking about talking to my dr. about possibly taking an ADHD medication. Have any of you tried this?It's kind of a new thing. If so, has it worked? I have been on Providgil (which is what truck drivers sometimes use to stay awake) I remember it helped for energy that and b-12 shots, but I had another problem with my heart racing and anxiety. Right now just trying a nutritional approach. Thank you for any advice.
