Hi, I am 18 years old, and I try to do anything now in order to give myself a healthier future after finding out I have High blood pressure(or borderline). I've read only a little bit on Asprin, and about how it helps people with their cardio, so I put myself on the daily asprin without any knowledge on long term affects. I did not tell my doctor, which I am suppose to, and I feel I made a big mistake. I weigh 130 and I am 5ft 6in and started the aspirin intake about a couple of weeks ago. I was taking 325mg of aspirin every night, and understand now that it is rough on the stomach and causes all sorts of problems, ulcers etc. I need to know more bout this, and I have no addiction or anything. I wan't to know if it is safe to just STOP using it, and what I should do to prevent bleeding etc. or if I should just find my way to a doc. I have no side affects known to me yet, other than feeling light headed at times and having sharp head pains, which I've had before. Please if somebody could help me with this. Like I said, I am 18 with no knowledge on health issues. Thanks...
