Addiction - When is it too much?

[lasciviouslizzy]

Evening, this will be SWIM first post on here so bear with me if i waffle.
Just had 40mg of Equasym (generic methylephenidate) and throughout the day swim has probably taken 6 20mg tablets throughout. more than swim usually takes.

swim usually takes about 100 mg a day, prescribed to take 3 x 20mg daily but obviously never works out that way.

obviously swim is worrying about how much is too much and what this is going to do to me if i go on like this.

Equally swim goes cold turkey for about a week a month with no real need to have more until swims due the next prescription.

does anyone else do this or is swim alone?
