Quick story.
Marijuana helps my creative process a lot, because I can get excited about an idea and just run with it. The only problem is that sometimes I get so excited, I feel my heart racing a million miles an hour and I start having trouble taking deep breaths.
So one day, I get high. I start getting excited about a concept and I was thinking a million miles an hour while walking over to the bus. Adrenaline kicks in and my heart starts racing too. Then I notice I'm having a hard time breathing. Pretty soon, I'm not thinking about that exciting concept anymore, but the prospect of myself having a heart attack. It was around the time I was producing Party Hearty, so I had researched sudden heart attacks in young people quite a bit; I knew all the symptoms. I was recognizing those symptoms in myself. I started getting nervous. I wondered, what would be the irony of I were to die the same way the character in my movie dies? I tried to take deep breaths to calm myself down, but I felt like I had just ran two miles. I walked on, hoping it would stop. It didn't. The more it kept going, the more certain I was that it might just happen, the more anxious I got, the faster my heart would beat, and the faster my heart would beat, the more convinced I was that this was it. In the back of my mind I wondered, "Even if I survive this, I'm young. This shouldn't be happening to me. I've got some serious health problems." I swear, I started to feel my neck stiffening up.
So, thinking I had a very limited time to get help, I ran over to the Women's hospital that I happened to be walking by. Surrounded by pregnant women in the ER, they pumped me full of sedatives. My heart was running at about 185 bpm. Basically I had a panic attack for the first time.
The lesson here is, while it might be fun getting excited about ideas. Don't get too excited. It could land you in the hospital with a big fat bill to pay later. Be warned.
