Medical scare I didn't need

Lets go back a ways.
In 2007 when I was IN the VA Homeless Veterand Domicilliary in Dublin Ga, I had been out to smoke a cigarette, when I got up to come inside I felt dizzy, by the time I made it into the building and hit the elevator button, I was extremely dizzy and nauseated, I passed out when the elevator got up to my floor.
I spent 5 days in a hospital bed enduring all kinds of testing, but they never found anything.
In 2017 I had just taken my BP med, stood up to go to bed, that same clammy pouring sweat dizziness and nausea hit me. I went to my hands and knees and crawled to my bed.
That happened again in another apartment. Each time I told people about it they said
"Jerry you're having a heart attack, get to the hospital" I did that once, no sign of a heart attack.
SO--- Last night my relative and I were in my back yard just after dusk, I'd had a glass of wine cooler, we had shared a joint.
It hit me again. THIS time, I was not alone and it scared my family members to death.
I was almost insensate much of the time, lying on the deck just feet away from my bed, but they couldn't get me up.
Between the three of us (minimum help from me) I got to the floor next to my bed.
I told them to leave me there, and a couple of hours later I managed to get up an crawl into bed. If I had called out, they would have come to my aid, but I just wanted to get into my bed.

I slept 6:08 and have now been up for about 3 hrs. I still feel weird, but I'm really alright.
My vitals this morning were "patently normal", BP was better than usual.
So now what? If I share this info with the stemcell people, they will most likely postpone my treatments, which should start in just over 10 days
