Dosage change

Hi everyone! I started taking 30mg about three weeks ago and it’s been nothing but life changing. I am finally able to focus, do chores without that excessive mental burden, brain fog and I am much calmer. I haven’t quite felt any bad side effects whatsoever, maybe insomnia once or twice. Anyways, since my body reacted very positively to this dosage, my psychiatrist suggested me to raise my dosage to 50mg but I’m worried that it might make my body used to this dosage and in case I have bad side effects and decide to take 30mg again, I won’t fully experience the amazing benefits of this short but amazing three week period. What’s your guys thoughts?
