My muscles shrink very fast if I don't lift. If I don't do anything (weightwise) for 2 months I can lose up to 20lbs+ of mostly muscle. It's so hard to take days off, I feel like I'm lazy or cheating myself from gaining.

So basically I'm asking would 3 days of rest make me bigger more so than if I lifted for another 3 days being in my situation though.
If your muscles shrink that quickly, they are in a constant state of transient hypertrophy because you are working them too hard. If there is a noticable loss in size after one week, that just isn't normal. With all the overtraining you do, your muscles are staying constantly swollen with blood plasma.

It isn't actual size, take a rest!!!! Its not possible to lose muscle that quickly, especially if your diet is in check. It sounds as if you are obssessed with lifting, you need to take rest.
