Heya all,

As the title implies I recently switched from Concerta (27 mg) to Vyvanse (20 mg) because I had heard very wonderful things about the latter and upping my Concerta dosage wouldn’t be ideal given my blood pressure. I’m about six days in to the swap and quite honestly I feel like shit. Like, obviously I’m experiencing withdrawal symptoms from a stimulant I took habitually for years but this still sucks. I’m curious to hear from others who have had the same experience, particularly about how long the adjustment period was.
