found another thread re: ritilin
I tried the Ritalin LA and didn't think it lasted more than about 5 hours.Just wondering if anyone knew how long Ritalin LA lasted through out the day, They said take one in the morning and one at lunch. Is it long enough to get through afternoon and evening activities.I dont think so lisa, I think it is just to get through the day. But I am not 100%. Perhaps have a look at the med on the web or search the pharmaceutical company that made the ritalin and see if they say.I've tried that, I can't find too much on it. Thanks
