Woah. 5mg XR is an extremelyyy low dosage. For comparison I’ve been taking 20mg XR and 10mg IR daily since I was 16 I believe. I also try and take breaks as often as possible. Definitely keep your dosage low like you have if you continue taking it. If you feel like you need a booster pill in the afternoon don’t increase your XR dosage, just add a 2.5 IR pill to some of your afternoons.
