Welcome to HW Definitely give those meds time to work, it takes a long time...6-8 weeks like olivia said. Do not do anything with your meds until you talk to your doctor, ever. Didn't mean to sound harsh, but you cannot be changing any doses, going off meds without talking to your doc.
It's hard though to talk to some of these docs sometimes and I understand that. The solution to that is just to be firm in asking questions and getting answers. Don't feel bad, don't be afraid. You are the patient. If you don't speak up, then you run into problems. It took me a lot of time to speak up with my pdoc, mostly b/c our appointments are literally 5 minutes long, and I always feel so rushed that I can't say anything. Now I just spit it all out whether he likes it or not. It's my appointment time and I am going to discuss what needs to be discussed.
Your doc will listen to you. Prepare a list of questions and bring it with you. If you have an opinion on a med/dose, tell him/her. I do that all the time. Sometimes my pdoc agrees and goes with what I want, sometimes he does not, and if not, then I do my best to respect his opinion, b/c he is the professional. And I do trust him.
Hope this helps. Give those meds lots of time, it's tough. Keep posting and let us know how you're doing.
