Day 10 on Duromine

Hi,

I'm on my 10th day of Duromine and i have had headaches and sleepless nights since day one.
I have lost 8kgs because i also do 5kms in the mornings and i eat clean.

I cant stand the headaches anymore, i don't think the daily misery is worth it for me. Do the headaches ever stop?
I also get nauseous but i realized that if i eat an apple or drink water the nausea goes away.

I'm thinking of quitting and just continue with my morning walks and healthy eating.
