Pretty easy for me to get drunk, very easy actually, as I don't drink and have a low tolerance.
I've never had much use of drugs or any substance abuse for that matter.
but...
Just a warning. I've taken Ritalin on and off for years and really started to love it because I could just "work, work, WORK!!!!" on the drug.
Before I knew it I got up to taking up to 5-10x my daily dose and stayed up for over 2 days!
I've got a resting heart rate in the 44-52 range and my heart was idling at 100-120 bpm.
If you take more than the therapeutic dose you can get a pretty damn good high. For me if I wasn't focused on work the high could could/can become very sexual, meaning I just can't keep my hand off my cock jerkin to the craziest hottest things I like.
I actually though about coming here and starting a thread on that basis and telling people to drop their affiliate links and I'd sign up, but it'd be a bad idea.
What caused me to stop was one of my work binges, a high dose gives me really bad dry mouth and though I've always had real good teeth, I had mild gum recession across most of my mouth within a period of 36 hours.
Prompted a dentist visit (hadn't visited in 12 years) turns out my mouth is very healthy and only 1 very mild cavity. The dentist even told me I had a "beautiful mouth."
Ritalin isn't really addictive, but the thought of the high as an experience has a pretty good allure that crosses my mind time to time.
Just use coffee now, and I bought a latte machine.
Anyway, follow the doctors advice and don't let things get out of hand. Only one tooth in my back has a fair amount of root exposed from it. Recessed gums do not grow back. They are fixable but it will cost $3-6k to fix my mouth, my dental insurance doesn't allow that for another year (so people don't sign up and cash in).
It's so mild I'll just get the back tooth grafted. They take chunks out of the roof of your mouth and the results are pretty good. The Dentist told me that as long as I took care of my mouth I probably wouldn't need to graft it for years, based off of my mouth's history.
