Who has sleep problems when taking preworkout supplements?

I am currently taking the Insane Lab's Psychotic and I have problem with my sleep activity like I should ideally have a 7-8 hours straight sleep so that my workout will have its intended effect but lately i have trouble sleeping when i take the said supplement. I just can't stop taking it especially on days that I eat less because it gives me the strength

That stuff gets you way jacked up... I cant handle it myself hurts my veins.

That stuff is wack. Heard its addictive and once you're on it you cant get off it.

preworkout is full of caffine isn't it? Probably why you aren't able to sleep too well

You shouldn't use them frequently.
