Feeling Floaty After Taking Mental Health Medication

I've been taking my meds now for just under 3 weeks, I feel weird to be frank. I was prescribed sertraline 25mg once daily by my therapist and then my obgyn, who I went to for a blood test and had not asked for any medication, prescribed me Buspirone 5mg twice day. I've been taking the Sert every day but only one Busp instead of two, I know I should be following the directions but I thought it wouldn't be so bad if I took less than recommended. I feel off, like I'm floating through instead of being an active part of my life. I'll admit the meds have helped me calm down and not freak out over the smallest inconvenience but now I feel all floaty all the time. I was wondering if anyone else felt this way with these meds or if I should talk to my Dr?
