Tonic / Healing Boost effect

[Angel Daggerfury]

I can't figure out what's causing this & what I'm doing wrong. Anyone else have this problem: about 75% of the times that I tonic, it shows the tonic being used from my inventory & the +#### whatever hp added in green above my head, BUT my HP bar remains the exact same, as if I never tonic at all. It's not lag, coz even like 30 seconds later, my hp regenerates over time, it never adds the automatic +#### to my hp. Same goes for using the Healing Boost on weapons, I use it, the green numbers on my head show up, but my hp bar remains the same as if I never used the Healing Boost skill at all.

If ur cursed by some gypsy or taunted or whatever, can u not heal ur self? That's the only thing I can think of that might not make tonics & the healing skill not work.
