I'd say you have what I refer to as pre-hppd... If you have to force it on, then it is in a mild form and will very likely go completely if you stay sober, get healthy, eat well etc. At the very worst, you will just stop looking for it (I have a feeling alot of these visual issues were always there, we just filter them out perfectly, pre-drugs)
I went through this stage and ignored it (this was before the internet!)... It can become hellish, but only by pouring fuel on the fire...
No point getting stressed about it now though, I'd suggest not even bothering reading further until you try the sober/healthy approach and see what is really going on... but the most important thing is to stay sober. Your body/mind is ringing out alarm bells, you have to listen.
