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.
I tried doing the same switch last week and made it four days before switching back. Vyvanse did almost nothing for my concentration, it just made me irritable and unable to sleep.
Simply to add a competing anecdote to an anecdote: vyvanse does great for my focus and even helps me sleep under the right circumstances. YMMV
Interesting, do you take it in the morning or later in the day?
