adhd
"45 year old woman, 138lbs 5'7".
Started at 25mg and titrated slowly. Noticed within a week my stress responses improved. Continued to increase as no change to organisation, memory or attention. Felt ok even at 100mg. Then since I started 120mg, I feel quite unwell. I don't think I'm unable to sustain this dose as side effects are strong: nausea after 1hr of ingestion, tiredness, feeling as though I've had too much strong coffee. The S/E definitely more pronounced if I'm not doing anything so I try and stay active and never take this on an empty stomach! 
I'll give it 2 more weeks at 120mg (which will be 6 weeks total) then gently titrate down. It gives me palpitations, too, which make me unhappy. 
I get this free on NHS in UK."
