Are the meds always tough in their start?

In fact I start to feel the side effects of mines… One pdoc was saying to me in the past, that in our worst states, we don’t even feel our meds… That was the case for me too before… My Zyprexa was like a candy for me before lol… But now that I pay efforts and try to change, I feel them. I can be dizzy or too smashed or too tired and its all changing in a day.
Were your meds tough for you too in their start? Will I get used to the side effects?
Ok, I don’t blame them for everything, there’s also my illness now, but its tough yeap… I get even nauseous and weak per moments…
Take care all!
