From experience i can tell you that low daily ground coffee consumption can lead to anxiety ,paranoia,  palpitations, cravings, and a strong diuretic and bladder irritant effect.For some people its extremely unhealthy.

Well, does anyone else problems with muscle cramps after caffeine (mostly coffee) ?. If i drink 1-2 espressos, which is not that much, might be somwhere between 70 – 200mg of caffeine, im much more prone to sort of muscle cramping or at least fasciculations. Does anyone else have some experience with this ?

I enjoy my coffee. (Although I began drinking it way too young.) I have coffee in the morning & occasionally a cup after dinner; and I drink tea all day long. For 40+ years, I've had no problems related to drinking it. I guess it's a difference in metabolisms.

I've been slamming a lot of preworkout lately. I've gotten so hyper aware and paranoid that I've started over analysing myself like when I was a kid. I'm honestly really fucking scared because I haven't really known who I am for the past few days…

I abused pre workout which is extremely high I'm caffeine for about a year. After a year which was 4 months ago. My heart started beating extremely fast and I could see it beating out of my chest. It takes 2 hours to get to the nearest hospital and I was pretty much paralysed and could barely move. It was the most pain I have ever felt in my entire life and I thought I wasn't going to survive. My dad rushed me to the hospital but took 2 hours to get there. When I arrived, the pain had stopped and I seemed fine but my heart still was very tight. I had some tests and it came back fine and apparently it was nothing. The doctor said that if i took what i usually take which is 2 scoups of pre workout that day then i would of had a heart attack and most likely died that night due to it taking so long to get to the hospital.It has been 4 months and haven't been back to the hospital or doctors and I still get these very painful attacks but no where near as bad… even though I am off of caffeine… I chose to abuse caffeine and it has clearly messed my heart up. I really don't want anyone else to go through this and I feel it is going to stay with me for my whole life. I am only 18 years old and already have heart problems. I just wish I could have not been stupid the past year and just take pre workout in moderation. If you are still reading this then never abuse caffeine…

Too much caffeine gives me that " chuckles I'm in danger" feeling.
