First time last night

It's been just over 12 hours since I injected, and I've already noticed feeling full I couldn't even finish my breakfast, which was bran flakes and a banana.

Does anyone have any tips to help me get through the first week?

So far, I haven't experienced any bad side effects, except for almost passing out after the injection due to my fear of needles. However, the actual injection was painless and much better than I expected.

Thank you
