Sparks symptoms and conditions

Has anyone experienced vision problems ? Seeing red and green dots ?

I've been taking it for 3 years, 100mg - 200mg/day.
- My sex drive increased
- I feel productive and optimistic
- I haven't gained or lost weight that hasn't been directly proportional to my diet/exercise. I am 130lb 5'7" 25yo.

My jaw feels tight. If I go for long periods without eating, I will begin to grind my teeth, but then if I eat I'm okay.
In the beginning I noticed little changes in my body, like little tingles zapping through me (they felt good) and would feel little sparks of what felt like contentedness/joy that were unrelated to anything going on in my head or environment. Also in the beginning (first month, two) I would come home from class/work and fall asleep and take like several naps throughout the day if I could. I never had the cool dreams, though. The need for extra sleep will go away.

Needless to say, I love this drug. It's the best thing to happen to my adult life. I recall feeling useless and wasted and having no energy for life and I am now on my own, making real money, friends and taking care of myself in a neat city. if it weren't for the prescription I'd probably be living at home eating cookies and working for $8/hr at a shitty job.
