So I was testing different ROA's for Ritalin and I found that taking Ritalin sublingually was very effective.
From what I read, sublingual has a higher BA than oral, and oral is considered quite low.
Everything was going good without much side effects, but lately, after a couple weeks of this ROA, when I try my Ritalin tablets sublingually, I started to build up a pain around my heart, and it extended to my left arm. Some of the worst side effects for your heart. I would also have trouble maintaining a calm breathing rhythm. So this is getting close to a 'heart attack' I would guess. Eventually the side effects would taper down after half an hour of discomfort and I'd feel fine.
This would happen with even with 10mg sublingually.
However, if I take 20mg orally, or even 40mg orally, I don't get any of these side effects. I can take anywhere from 2x to 4x as much ritalin orally compared to sublingually and I don't understand why I don't get that pain in my chest?
I read somewhere that sometimes its just heart burn or acid reflux, so I took some tums, but I don't think it made any difference.
I gave up on sublingual for the time being. Does a higher BA also increase the side effects? Maybe the drug is entering my system too fast? I even chew my tablets and swallow for faster effect, and I stil don't get those nasty side effects.
