2003 Honda Accord Driver's side A/C not cooling, but then c

Air Conditioning problem
2003 Honda Accord 4 cyl Automatic 80,000 miles

Hope my solution is easy.
A few weeks back I started noticing that my Honda's A/C was cooling very little. It's mid-summer here in S FL and it's no joke how hot it gets!
So I decided to add a sealer and more refrigerant. This made no difference on the cooling in the beginning and may have made the matter even worse. But. This is what happened after I added the refrigerant:
First symptom: The compressor would turn on and off multiple times within seconds. This happened only once, and went away when I let the car rest for about 45 minutes and hasn't returned since.
Second: I hope this is some automatic process, but after the above event went away, the car started releasing some type of gas or air for about 1 minute intermittently, and then went away. Also hasn't returned.
Finally, this is where I'm at right now: The passenger side A/C is cooling fine, but the driver (me!) Is hot since the A/C for the driver's side will not cool at all for atleast 20 minutes. After 20 minutes of driving, it starts to cool, but not at the same temp as the passenger. Additionally, while the a/c is not cooling for the driver, the engine is making a different noise when accelerating; sounds like an electric motor that revs with the engine. When it starts to cool again, that sound goes away.

Whew! Hope this info helps!
