Hi Priscilla - I would mention your fears to your psychiatrist, as they should take this into account and express WHY they're making the changes and WHY they're having you retested (depending on what we mean by testing here, if you're given certain assessment measures, those can only be administered once a year... so I'm not sure why the psychiatrist would want you retested, unless it's a different method than what you had in March). You are the director of your health care, if you are uncomfortable with something I urge you to speak with your provider.
I don't think you'll be "roadkill" - you may notice some lethargy; however, that should subside as you continue to take the medication, if it doesn't - inform your provider. Also, try to do things to help yourself in the AM when you first wake up - don't allow yourself to remain in bed, get up - start your day - this is easier said than done; yet, will be of most benefit to you. Sometimes it helps having a saying next to your bed that helps motivate you, then one in the bathroom to keep you going. It's hard AND I know you can do it!!!
Was there anything else I can help you with? If not, please provide a rating as to how you believe my service was. Thank you and best of luck!
