As a PD patient I have been taking Requip 16 mg and Stalevo(100,100,50,50) for the last 10 years. Now after DBS Requip intake decreased by 2 mg and Stalevo is replaced by Trivastal and Amantadine. Considering the experience of users of this forum is this substantial improvement? If yes has anybody experienced this before and what kind of side effects does this change have on the body? Thanks.
