"I have been on this medication for almost 11 years I believe that the capsule time released at least for me work a lot better because of the longevity as well as impact. The instant release a great but for me I have a past history with drug abuse in the instant release seems to give a high effect for about an hour and then you come down as well as you don't feel the effects of the medication working properly. Again I can only speak for myself but the time released helps to keep me at an even keel and I stay level for the whole day through no highs and lows."
