I'm not quite sure what help you want.
I do know that you feed dry food and do not intend to change to wet, so that alone will mess with any BG numbers.
Also, without numbers, I don't want to be recommending any suggestions.
You mention that you are thinking of using Lev, but have no rx from the vet.
Unfortunately, you neglect to mention what insulin you are using and you have no signature with the basic info.
To be direct, it would be dangerous to recommend anything more than the following:
1. Diet change from dry to wet to be started.
2. Home testing needs to become regular, daily.
3. Spreadsheet with some numbers of testing, and notes on what food was fed at what times to be created.
4. Signature to include insulin used and important notes on feeding dry
My guy dropped an average of 150 points due to dose increase and diet..now
This size of drop is meaningless without knowing the number before the drop, at what point that number was taken, and the length of time it took to drop 150 points.
He is stuck in the threes from end to end
I have no idea what 'the threes' means, and do not want to guess.
You could mean 300s in which case it's expected because you feed dry food.
I have no idea what 'from end to end' means. If you mean from one shot to the other, where is the 150points drop?
His dose started at 1 BID then 1.25 BID then !.75 BID for the past three weeks
Without knowing what insulin you are using, I cannot comment.
By stating you started at one dose and then increased twice does not help without knowing how long was each dose held and what were the BG numbers on each dose, and finally why the dose was increased each time.
Would you increase by .25 .50 .75 1.0 or leave it alone at 1.75 ?
Based on the earlier noted missing info, I don't think a single person will give a suggestion for any sort of increase. What protocol are you following that would suggest an increase of 1.0 on a dose of 1.75, which is almost doubling the dose?
If you could provide the necessary data as requested above, I am sure some people will gladly help you with your decision making.
