View Full Version : Second Does of Methylphenidate

06-26-14, 10:29 AM
When I wake up in the morning I eat break fast and take my first dose of 20mg IR Methylphenidate. Then about 2.5 to 3 hours later when it starts to wear off I take my second dose, 20mg IR Methylphenidate, but I'll only feel the effects of this dose for another 30 minutes or not at all then I crash not even a quarter of the way through my day. Does anyone know why this happens or have similar problems with Methylphenidate? If anyone could give me advice on how to make my second dose last longer it would be appreciated. Thanks in advance
