I have been taking Effexor 37.5 for 3 weeks and it has made me extremely short of breath. Anyone else experience this? It’s like it has lessened the benefits of my trelegy inhaler. I did not take it last night because I want off this crap and I feel worse now than when I started it. Any advice? I know I can take Prozac but not sure if I can just switch. Seeing my Dr. tomorrow but I absolutely will not be continuing this medication if she ask me to. NO WAY!!
