Tried ritalin (normal), ritalin SR,
Concerta and amphetamine.
Concerta gave me something but felt something missing, normal ritalin was terrible, OD and came into "cocain waves" (very high, and straight to the bottom), amph gave me more but I didnĀ“t eat, and felt a bit anxious, ritalin SR was, and is my favourite, works as a charm.
