I am a man age 42, an engineer with a lot of mental workload. My psychiatrist gave me ritalin 10 mg to overcome my depressed feeling, sleepy mood and passive condition (lack of confidence in my activities and work). It helped me with my concentration too. I took it a quarter, half or 3 quarters. The good feeling and active mood goes away after a couple of hours and I have to take a new piece again. The doctor has told me my total daily dosage of ritalin should?t go beyond two tablets. Recently I am taking metride 18 mg (prolong- release methylphenidate hydrochloride). It is not a breakable tablet, but one tablet keeps me positive all days long. The problem is I feel stressful and fearful when I get it, just opposite to when I take ritalin. Ritalin makes me very happy and laugh around a lot, which is not good for my job situation. I am thinking about microdoses of cannabis, as read about it in papers. In general, I need something that boost my self-confidence, gives me concentration, takes me out of sleepy and tiered mood and makes me active. And more important, a safe dosage that does?t damage my brain?s cells. I appreciate if you can give me help and idea to overcome my problem. For sure, for any usage and taking medicine, I go to my psychiatrist first and I receive his prescription. However, I need your medical help and idea to know what I have to look for. Thanks.
