Sulbuthiamine is a potent cholinergic and actually a Supra-physiological dose of vitamin B1 you can take and test it i used it makes you calmer and alert. I did not feel any difference on short term memory but it really enhances episodic long term memory.
Brother snri fucks up your short term memory because of it my adhd went to roof.
It also kills libido and genital sensitivity it is worse thing after finasteride. They had to give me because of panic attacks yet, it did not work well. Then we started mph i normalized even panic attackes and anxiety resolved. Then he told me to quit from ssri and i became much more better.
So go with mph or bupropion.
