These are wise words. If you are manic depressive you should get checked out so that you can start managing your condition.
I had a dose of stimulants trigger a rather crazy manic episode one of the last times I used stimulants. It was tons of fun and I rather enjoyed the ensuing days of no sleep, feeling like I was god/Jesus, thinking I understood the universe in its entirety, etc.
It was weird. I took a large dose and it trigger something in me. For those next 5 to 6 days i didn't redose.... I didn't have to. It was like I was high on my own fucked up brain chemistry.
Like I said, it was fun but the fallout was not. Towards the end of the experience (day 5 I think), it was late at night and I was outside on my roof practically naked for 5/6 hours. If was only 40 F outside. I was dancing on the rough convinced my dance moves were somehow controlling the stars, and in turn, the entire universe. I was god conducting my universe. I loved the experience, but the cops showed up and hauled my ass off to the hospital. Spent a couple weeks in the psych ward.
I'm still not sure if I'm manic depressive but doctors tell me that was my first manic episode and I should avoid stimulants. The dose I took was large but not that large. Definitely not big enough to keep me high for 5 or 6 days. It triggered something in my brain.
So be careful.
