Hello, Thanks for your answer. I bought 5htp and Gabba to try it out when I'm wired Also, yes paracetamol is a painkiller but it really puts me asleep. When I'm really wired, I take 1g but it usually does not work and I wake up in the next hour so when I wake up I take another 1g. It really makes a difference for me. They also sell Ibuprofen or paracetemol (advil PM or tylenol PM)+ Diphenhydramine. Diphenhydramine puts you asleep but I noticed I have a lot of troubles to wake up the next morning. Yes you fall asleep but the next morning you still fell asleep for long hours... Give it a try, maybe it's different for you.
