Clomipramine to Luvox, advice?

Currently on 75 mg of clomipramine (previously 150) but thinking of switching to Luvox. Clomipramine is just making me so incredibly tired that I’m unable to do anything 😭 which is sad because I do feel it working but even lowering my dose hasn’t helped the tiredness. Has anyone gone from clomipramine to Luvox, and if so what was the withdrawal/switch like? Also what was your motivation like on Luvox?
