I was in your position once also. I have a very hard and stressful job. It is fast paced and I cannot keep up with everyone. I decided to take
Ritalin or other
amphetamines such as Adderal. This helps me keep up. In fact, helps me become faster than some other people who used to be faster than me. It even gave me the chance to get a 40 cent an hour raise. The comedown however is hard, harder than you would imagine without trying it. I do not recommend you to do this if you know you don't have the willpower to stop. I'm not addicted to them but I prefer taking them before work. Some days I stop just so that I don't get a physical addiction to them. It's strictly psychological and I can overcome it. It really is up to you to decide. Ask your close friends whether they recommend it or not. You'd be surprised about some reactions if you ask them in private so there is no peer pressure on the issue. All I can say is I love them better than a Rockstar energy drink. With that, I hope you make the right decision.
