### input:
I have a very poor attention span, i cant concentrate on a tv show, or even when someone is talking to me my concentration lasts a stupidly small time. I was considering asking my GP if he could prescribe me ritalin. I am not sure whether i would need any further testing or anything before hand. I do not want the drug for any form of recreational useage and in fact i would actully prefer one that increases concentraion without those side effects. I am not a fan of drugs that can have uses other than what i need them for eg when i have asked for sleeping pills or painkillers before i have specified i do not want opiates, benzos etc.I was wondering if you think it would be a good idea to ask my dr for them, or if there is an alternitive to them that you think would be betterAdditional info, i am 21, male. I was been diagnosed with bpd a few years ago. I am not on any medication. I used to drink alcohol too much but i cut down a few months ago to a fraction of the amount i used to drink. Smoker - around 10/15 per day that i roll myself from tobacco.

Degree understand your concerns went through your details. I suggest you not to worry much. You are supposed to refer to concentration and attention as two. Attention span for any adult is maximum 30 minutes. Sometimes, a person can be attentive to an interesting thing for more than 30 minutes, such as movies or games. Concentration is attention plus understanding. For this too, span of below 30 minutes. If you are able to make your studies interesting and based on variable principle, your concentration level can be increased. Concentration comes only when you are interested in what you do. So please be passionate towards what you are doing or do only those things which you are interested in. It is also possible to improve your concentration level with the help of yoga, meditation and breathing exercises. Psychotherapy techniques should suit your requirement.
