Strong effects on taurine

So i just tried taurine because i heard it helped some people, and the effect it has on me is really strong. It feels like kinda like drinking too much coffee. A energie feeling in my chest maybe also like riding a rollercoaster. Its not exectly unpleasend and i do feel more energy but its also too much for me and i cant sleep. Taurine is supposed to have a more relaxing and calming effect so this is really weird. Has anybody had a similar experience? I would be insterested in how this would change over time because its clearly doing something, but my sleep is too important for me right now.
