You should probably do some further investigation toward identifying the cause of the low blood pressure. I imagine that the most probable cause of low blood pressure in a generally "healthy" person would be adrenal insufficiency. I have the same problem. I find that increasing salt intake relieves symptoms. Here's an overview about the relationship between salt cravings and adrenal fatigue:
