I've been on Avalide 300mg for a couple weeks, Avapro with HCT, a diuretic. I've been on many different BP meds over the last decade or so and I've got a little experience on how the different types make me feel. Your stoned or 'out of it' feeling is normal. Do you have problems focusing your eyes a little too? I was feeling pretty dazed on 300mg so I started breaking the pills in half. I know, I'm bad for playing with my medications but I can't stand feeling that out of it. It really comes on strong in the afternoon about 4-6 hours after I take it.

My Doc is always saying "You shouldn't be experiencing much of any side effects" regardless of what I'm taking and despite what I tell him. Beta-blockers also made me feel out of it too with the same response from the Doc. They all seem to be clueless about side effects.
