Struggling with Strattera and POTS flare, need advice

I began Strattera a couple of days ago and Dr said the effects from 25mg I'm on might not be felt for 4 weeks. Since it's not a stimulant the energy side effects may be seen with your greater ability to focus. I was concerned about sleep too that's why we chose Strattera. I'm going in for an RA and POTS eval and testing Friday too. Are you taking more than 23mg per dose?

Extra note, I take metoprolol for POTS (25mg) and I’m also on Prozac (50mg). Prozac increases blood levels of Straterra, so I’ve been on 40mg with no changes to be made for at least a month. My BP usually hovers just a bit above what’s considered low. I’m seeing my psych next week and if I’m not doing better we’ll discuss options… I’d consider asking to up metoprolol a bit and see if it helps but I’m not sure if that’d push my BP over and end up not helping. Plus I won’t be able to see my cardiologist because of school so I’m not sure if he’d be okay changing things. Balancing it all is so complicated!! I’m very used to medication trial and error but it’s still so frustrating 😑
