self medication

has anyone had to find there own levels when it comes to medication i have been at it 10 days now as i cant stomach the amounts they tell me to take in one go i feel better not taking any but i think its the beta blockers that are the problem because if i take all the others and not them im fine and if i leave the others out and just take the beta blockers then the problem starts been on bisop now on carvedilol but having to take in half tablets throughout the day
