Link between working memory, stress, anxiety, depression and stuttering

Working memory in human beings can be analogous to the computer RAM. More the RAM a computer has, faster the computer is. Having more RAM in a computer can help the computer to perform faster operations and multitasking. Similarly, availability of more working memory in humans will enable to do better multitasking at faster speeds.

For the past 4 days I am taking Ginkgo biloba 2500 mg extract. Also, I am walking 30 minutes everyday evening around 8 - 9 pm.

Composition:
Each capsule contains 50 mg of standardized extract (equivalent to 2500 mg of dry Ginkgo biloba leaves); contains 24% ginkgoflavonglycosides and 6% terpene lactones.

Positive effects:

• Good mood - really good mood with inflow of innate happiness
• Very less anxiety - anxiety was extremely less while speaking
• Almost no stuttering - very good fluency with more talkative nature; No anxiety while calling through phone.
• Increased libido - With good inflow of happiness, I am in a mood to look forward for sex. However, not strong erections.
• No headaches - really no headaches and my head is really very clear
• Able to get ready faster in the morning - around 1 hour to 1 hour 15 minutes. Before, it used to be 1 hour 30 minutes.
• My car driving speed increased tremendously. I am able to drive at 110-120km/h speed and at the same time enjoying music. (Earlier, whenever I accelerate to 110-120km/h speed, all my attention used to focus on driving and on the road. And also, I used to feel my adrenaline rush. Whenever car used to shake due to road imperfections, my adrenaline increased and all my attention focused on road and steering wheel). But, now, I am least bothered about the car shake and able to enjoy music. 2 days back, I was driving in the fast lane at 110-120km/h speed. I made 3 cars to change to slower lane to give me way, which were going in front of me. Such a tremendous speed of information processing never happened to me before while driving.
• Music is enjoyable very much.
• I have started watching movies also. Earlier, I lose patience in watching movies continuously.
• Able to make phone calls to relative without much stuttering and anxiety. This was not at all possible before. Earlier, I used to have fear of stuttering and anxiety of talking over phone. Due to this, I avoided calling my relatives which led to some misunderstanding amongst my relatives.  

Negative effects:

• More sleepy - sleeping time increased to 8-10 hours.
• Not very strong erections. But sustained increase in libido is observed. This libido seems to be linked with dopamine levels. Actually before taking this Ginkgo biloba, I was taking bupropion SR 150 mg for four days. Then I stopped it for 1 day. Then, the next day, I took this Gingko biloba. So, the residual bupropion remained in the body would have caused this increased libido possibly.

Neutral effects:

• Not significant increase in speed of working - but slightly increased motivation to remain in a task is observed. Still inertia to initiate the planned work is there.

Update on 27 June 2012:

• Today I had to chair a meeting. No anxiety was there. No gasping for breath occurred. No pronounced stuttering also occurred. However, I felt little bit of vocal blocks when try to speak. But, once I started, then there was no stuttering. In a meeting, whenever, I had to interrupt a talking person, I felt some vocal blocks. So, I kept quiet. Otherwise, my stuttering was manageable. I cracked some jokes also.
