Perfect timing! Yes, I feel the exact same thing.
I’ve been on titration with medikinet XL with 20 mg for a month which was ok, then after a review got told to try 30 mg for two weeks and 40 mg for two weeks.
30 mg made me feel a bit stressed at work, but nothing that bothered me. Like having 3 coffees when you have a lot going on and you need to get things done quickly. As you say, this feeling only lasts for a while only.
Now I’ve moved to 40mg and I hate it. Roughly 2-3 hours after taking it, I get exactly what you describe. I’ve been trying to explain it as a 7-coffee panic. Same situation as the above but with so much coffee in my body that I’m at the edge of having a meltdown and bursting into tears.
This, of course, comes with high blood pressure and heart rate. My understanding is with extended release you get a first “peak concentration”, then lowers slowly, and you get a second peak at about 4h or so, depending on formulation. Yesterday, at a time I think matched the second peak roughly, I was watching a stress-free TV show on the sofa, in a stress-free environment with no tasks to do… And suddenly this feeling came in and I had almost 90bpm resting heart rate for no reason when I’m normally in the low 70s.
I hate it and on Monday (I have my next medication review) I’m going to ask for alternatives or to get put on 30mg. That made me productive and motivated but without feeling like I’m being motivated by panic.
Op, I’ll try to remember to comment here about what the doc/nurse says tomorrow after that review.
